0023675: P-curves of a face are out of the domain of the face.

Analyzing of 2D-curves' boundaries.
Tolerance range computing was changed.

1. Function Validate(...) returns BRepCheck_Status.
2. For faces, whose pcurves is out of domain, status BRepCheck_OutOfSurfaceBoundary is returned.
3. For edges, which is out of face's boundary, status BRepCheck_PCurveIsOutOfDomainFace is returned.
4. Print warning, if status is not defined.
5. BRepCheck_Face::SetStatus(...) and BRepCheck_Wire::SetStatus(...) functions added.
6. ShapeFix::RefineFace(...) function and it draw-commands (ffixpcu and sfixpcu) are added. Command "ffixpcu" fixes a face with BRepCheck_OutOfSurfaceBoundary status. Command "sfixpcu" fixes a shape, which contains a face with BRepCheck_OutOfSurfaceBoundary status.
7. Trimming algorithm for surfaces changed (ForceTrim method is added).
8. Small correction of output of "checkshape" command result.
9. MinMax() and RealMod() functions are added.
10. Fixing of some shapes from test base.

Faces, which based on periodic or closed surfaces, are not controlled.

+
+    Version 2.1, February 1999
+
+    Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+    51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+    Everyone is permitted to copy and distribute verbatim copies
+    of this license document, but changing it is not allowed.
+
+    [This is the first released version of the Lesser GPL.  It also counts
+    as the successor of the GNU Library Public License, version 2, hence
+    the version number 2.1.]
+
+### Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+### TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+-  0. This License Agreement applies to any software library or other
+   program which contains a notice placed by the copyright holder or
+   other authorized party saying it may be distributed under the terms of
+   this Lesser General Public License (also called "this License").
+   Each licensee is addressed as "you".
+
+   A "library" means a collection of software functions and/or data
+   prepared so as to be conveniently linked with application programs
+   (which use some of those functions and data) to form executables.
+
+   The "Library", below, refers to any such software library or work
+   which has been distributed under these terms.  A "work based on the
+   Library" means either the Library or any derivative work under
+   copyright law: that is to say, a work containing the Library or a
+   portion of it, either verbatim or with modifications and/or translated
+   straightforwardly into another language.  (Hereinafter, translation is
+   included without limitation in the term "modification".)
+
+   "Source code" for a work means the preferred form of the work for
+   making modifications to it.  For a library, complete source code means
+   all the source code for all modules it contains, plus any associated
+   interface definition files, plus the scripts used to control compilation
+   and installation of the library.
+
+   Activities other than copying, distribution and modification are not
+   covered by this License; they are outside its scope.  The act of
+   running a program using the Library is not restricted, and output from
+   such a program is covered only if its contents constitute a work based
+   on the Library (independent of the use of the Library in a tool for
+   writing it).  Whether that is true depends on what the Library does
+   and what the program that uses the Library does.
+  
+1. You may copy and distribute verbatim copies of the Library's
+   complete source code as you receive it, in any medium, provided that
+   you conspicuously and appropriately publish on each copy an
+   appropriate copyright notice and disclaimer of warranty; keep intact
+   all the notices that refer to this License and to the absence of any
+   warranty; and distribute a copy of this License along with the
+   Library.
+
+   You may charge a fee for the physical act of transferring a copy,
+   and you may at your option offer warranty protection in exchange for a
+   fee.
+
+2. You may modify your copy or copies of the Library or any portion
+   of it, thus forming a work based on the Library, and copy and
+   distribute such modifications or work under the terms of Section 1
+   above, provided that you also meet all of these conditions:
+
+   1. The modified work must itself be a software library.
+
+   2. You must cause the files modified to carry prominent notices
+      stating that you changed the files and the date of any change.
+
+   3. You must cause the whole of the work to be licensed at no
+      charge to all third parties under the terms of this License.
+
+   4. If a facility in the modified Library refers to a function or a
+      table of data to be supplied by an application program that uses
+      the facility, other than as an argument passed when the facility
+      is invoked, then you must make a good faith effort to ensure that,
+      in the event an application does not supply such function or
+      table, the facility still operates, and performs whatever part of
+      its purpose remains meaningful.
+
+      (For example, a function in a library to compute square roots has
+      a purpose that is entirely well-defined independent of the
+      application.  Therefore, Subsection 2d requires that any
+      application-supplied function or table used by this function must
+      be optional: if the application does not supply it, the square
+      root function must still compute square roots.)
+
+   These requirements apply to the modified work as a whole.  If
+   identifiable sections of that work are not derived from the Library,
+   and can be reasonably considered independent and separate works in
+   themselves, then this License, and its terms, do not apply to those
+   sections when you distribute them as separate works.  But when you
+   distribute the same sections as part of a whole which is a work based
+   on the Library, the distribution of the whole must be on the terms of
+   this License, whose permissions for other licensees extend to the
+   entire whole, and thus to each and every part regardless of who wrote
+   it.
+
+   Thus, it is not the intent of this section to claim rights or contest
+   your rights to work written entirely by you; rather, the intent is to
+   exercise the right to control the distribution of derivative or
+   collective works based on the Library.
+
+   In addition, mere aggregation of another work not based on the Library
+   with the Library (or with a work based on the Library) on a volume of
+   a storage or distribution medium does not bring the other work under
+   the scope of this License.
+
+3. You may opt to apply the terms of the ordinary GNU General Public
+   License instead of this License to a given copy of the Library.  To do
+   this, you must alter all the notices that refer to this License, so
+   that they refer to the ordinary GNU General Public License, version 2,
+   instead of to this License.  (If a newer version than version 2 of the
+   ordinary GNU General Public License has appeared, then you can specify
+   that version instead if you wish.)  Do not make any other change in
+   these notices.
+
+   Once this change is made in a given copy, it is irreversible for
+   that copy, so the ordinary GNU General Public License applies to all
+   subsequent copies and derivative works made from that copy.
+
+   This option is useful when you wish to copy part of the code of
+   the Library into a program that is not a library.
+
+4. You may copy and distribute the Library (or a portion or
+   derivative of it, under Section 2) in object code or executable form
+   under the terms of Sections 1 and 2 above provided that you accompany
+   it with the complete corresponding machine-readable source code, which
+   must be distributed under the terms of Sections 1 and 2 above on a
+   medium customarily used for software interchange.
+
+   If distribution of object code is made by offering access to copy
+   from a designated place, then offering equivalent access to copy the
+   source code from the same place satisfies the requirement to
+   distribute the source code, even though third parties are not
+   compelled to copy the source along with the object code.
+
+5. A program that contains no derivative of any portion of the
+   Library, but is designed to work with the Library by being compiled or
+   linked with it, is called a "work that uses the Library".  Such a
+   work, in isolation, is not a derivative work of the Library, and
+   therefore falls outside the scope of this License.
+
+   However, linking a "work that uses the Library" with the Library
+   creates an executable that is a derivative of the Library (because it
+   contains portions of the Library), rather than a "work that uses the
+   library".  The executable is therefore covered by this License.
+   Section 6 states terms for distribution of such executables.
+
+   When a "work that uses the Library" uses material from a header file
+   that is part of the Library, the object code for the work may be a
+   derivative work of the Library even though the source code is not.
+   Whether this is true is especially significant if the work can be
+   linked without the Library, or if the work is itself a library.  The
+   threshold for this to be true is not precisely defined by law.
+
+   If such an object file uses only numerical parameters, data
+   structure layouts and accessors, and small macros and small inline
+   functions (ten lines or less in length), then the use of the object
+   file is unrestricted, regardless of whether it is legally a derivative
+   work.  (Executables containing this object code plus portions of the
+   Library will still fall under Section 6.)
+
+   Otherwise, if the work is a derivative of the Library, you may
+   distribute the object code for the work under the terms of Section 6.
+   Any executables containing that work also fall under Section 6,
+   whether or not they are linked directly with the Library itself.
+
+6. As an exception to the Sections above, you may also combine or
+   link a "work that uses the Library" with the Library to produce a
+   work containing portions of the Library, and distribute that work
+   under terms of your choice, provided that the terms permit
+   modification of the work for the customer's own use and reverse
+   engineering for debugging such modifications.
+
+   You must give prominent notice with each copy of the work that the
+   Library is used in it and that the Library and its use are covered by
+   this License.  You must supply a copy of this License.  If the work
+   during execution displays copyright notices, you must include the
+   copyright notice for the Library among them, as well as a reference
+   directing the user to the copy of this License.  Also, you must do one
+   of these things:
+
+   1. Accompany the work with the complete corresponding
+      machine-readable source code for the Library including whatever
+      changes were used in the work (which must be distributed under
+      Sections 1 and 2 above); and, if the work is an executable linked
+      with the Library, with the complete machine-readable "work that
+      uses the Library", as object code and/or source code, so that the
+      user can modify the Library and then relink to produce a modified
+      executable containing the modified Library.  (It is understood
+      that the user who changes the contents of definitions files in the
+      Library will not necessarily be able to recompile the application
+      to use the modified definitions.)
+
+   2. Use a suitable shared library mechanism for linking with the
+      Library.  A suitable mechanism is one that (1) uses at run time a
+      copy of the library already present on the user's computer system,
+      rather than copying library functions into the executable, and (2)
+      will operate properly with a modified version of the library, if
+      the user installs one, as long as the modified version is
+      interface-compatible with the version that the work was made with.
+
+   3. Accompany the work with a written offer, valid for at
+      least three years, to give the same user the materials
+      specified in Subsection 6a, above, for a charge no more
+      than the cost of performing this distribution.
+
+   4. If distribution of the work is made by offering access to copy
+      from a designated place, offer equivalent access to copy the above
+      specified materials from the same place.
+
+   5. Verify that the user has already received a copy of these
+      materials or that you have already sent this user a copy.
+
+   For an executable, the required form of the "work that uses the
+   Library" must include any data and utility programs needed for
+   reproducing the executable from it.  However, as a special exception,
+   the materials to be distributed need not include anything that is
+   normally distributed (in either source or binary form) with the major
+   components (compiler, kernel, and so on) of the operating system on
+   which the executable runs, unless that component itself accompanies
+   the executable.
+
+   It may happen that this requirement contradicts the license
+   restrictions of other proprietary libraries that do not normally
+   accompany the operating system.  Such a contradiction means you cannot
+   use both them and the Library together in an executable that you
+   distribute.
+
+7. You may place library facilities that are a work based on the
+   Library side-by-side in a single library together with other library
+   facilities not covered by this License, and distribute such a combined
+   library, provided that the separate distribution of the work based on
+   the Library and of the other library facilities is otherwise
+   permitted, and provided that you do these two things:
+
+   1. Accompany the combined library with a copy of the same work
+      based on the Library, uncombined with any other library
+      facilities.  This must be distributed under the terms of the
+      Sections above.
+
+   2. Give prominent notice with the combined library of the fact
+      that part of it is a work based on the Library, and explaining
+      where to find the accompanying uncombined form of the same work.
+
+8. You may not copy, modify, sublicense, link with, or distribute
+   the Library except as expressly provided under this License.  Any
+   attempt otherwise to copy, modify, sublicense, link with, or
+   distribute the Library is void, and will automatically terminate your
+   rights under this License.  However, parties who have received copies,
+   or rights, from you under this License will not have their licenses
+   terminated so long as such parties remain in full compliance.
+
+9. You are not required to accept this License, since you have not
+   signed it.  However, nothing else grants you permission to modify or
+   distribute the Library or its derivative works.  These actions are
+   prohibited by law if you do not accept this License.  Therefore, by
+   modifying or distributing the Library (or any work based on the
+   Library), you indicate your acceptance of this License to do so, and
+   all its terms and conditions for copying, distributing or modifying
+   the Library or works based on it.
+
+10. Each time you redistribute the Library (or any work based on the
+   Library), the recipient automatically receives a license from the
+   original licensor to copy, distribute, link with or modify the Library
+   subject to these terms and conditions.  You may not impose any further
+   restrictions on the recipients' exercise of the rights granted herein.
+   You are not responsible for enforcing compliance by third parties with
+   this License.
+
+11. If, as a consequence of a court judgment or allegation of patent
+   infringement or for any other reason (not limited to patent issues),
+   conditions are imposed on you (whether by court order, agreement or
+   otherwise) that contradict the conditions of this License, they do not
+   excuse you from the conditions of this License.  If you cannot
+   distribute so as to satisfy simultaneously your obligations under this
+   License and any other pertinent obligations, then as a consequence you
+   may not distribute the Library at all.  For example, if a patent
+   license would not permit royalty-free redistribution of the Library by
+   all those who receive copies directly or indirectly through you, then
+   the only way you could satisfy both it and this License would be to
+   refrain entirely from distribution of the Library.
+
+   If any portion of this section is held invalid or unenforceable under any
+   particular circumstance, the balance of the section is intended to apply,
+   and the section as a whole is intended to apply in other circumstances.
+
+   It is not the purpose of this section to induce you to infringe any
+   patents or other property right claims or to contest validity of any
+   such claims; this section has the sole purpose of protecting the
+   integrity of the free software distribution system which is
+   implemented by public license practices.  Many people have made
+   generous contributions to the wide range of software distributed
+   through that system in reliance on consistent application of that
+   system; it is up to the author/donor to decide if he or she is willing
+   to distribute software through any other system and a licensee cannot
+   impose that choice.
+
+   This section is intended to make thoroughly clear what is believed to
+   be a consequence of the rest of this License.
+
+12. If the distribution and/or use of the Library is restricted in
+   certain countries either by patents or by copyrighted interfaces, the
+   original copyright holder who places the Library under this License may add
+   an explicit geographical distribution limitation excluding those countries,
+   so that distribution is permitted only in or among countries not thus
+   excluded.  In such case, this License incorporates the limitation as if
+   written in the body of this License.
+
+13. The Free Software Foundation may publish revised and/or new

-The purpose of this document is to define and formalize one style of programming for developers working on Open CASCADE Technology.
-The establishment of a common style facilitates understanding and maintaining code developed by more than one programmer as well as making it easier for several people to co-operate in the development of the same framework.
-In addition, following a common programming style enables the construction of tools that incorporate knowledge of these standards to help in the programming task.
-Using a consistent coding style throughout a particular module, package, or project is important because it allows people other than the author, and the author himself, to easily understand and (hopefully) maintain the code.
-Most programming styles are somewhat arbitrary, and this one is no exception. Some guidelines have been excerpted from the public domain of widely accepted practices.
-This suggests that the guide will continue to evolve over time as new ideas and enhancements are added.
+The purpose of this document is to define a common programming style for Open CASCADE Technology.

-The names considered in this section are mainly those which compound the interface to Open CASCADE Technology libraries as well as source code itself.
+The names considered in this section mainly refer to the interface of Open CASCADE Technology libraries or source code itself.
 
 ### International language [MANDATORY]
-All names are composed of English words and their abbreviations.
-Open CASCADE Technology is an open source available for international community.
 
-### Suggestive names
-Names should be suggestive or, at least, contain a suggestive part.
-Currently, there is no exact rule that would define how to generate suggestive names. However, usually names given to toolkits, packages, classes and methods are suggestive. Here are several examples:
-- Packages containing words Geom or Geom2d in their names are related to geometrical data and operations.
-- Packages containing words TopoDS or BRep in their names are related to topological data and operations.
-- In OCAF, packages that define transient, persistent data classes and drivers to map between them, have similar names prefixed by 'T', 'P', and 'M' correspondingly (e.g. TDocStd, PDocStd, MDocStd).
-- Packages ending with ...Test define Draw Harness plugins.
-- Methods starting with Get... and Set... are usually responsible for (accordingly) retrieving/storing some data.
+Open CASCADE Technology is an open source platform available for an international community, thus all names need to be composed of English words or their abbreviations.
+
+### Meaningful names
+
+Names should be meaningful or, at least, contain a meaningful part. To better understand this requirement, let us examine the existing names of toolkits, packages, classes and methods:
+- Packages containing words *Geom* or *Geom2d* in their names are related to geometrical data and operations.
+- Packages containing words *TopoDS* or *BRep* in their names are related to topological data and operations.
+- In OCAF, packages that define transient, persistent data classes and drivers to map between them, have similar names prefixed by *T*, *P*, and *M* correspondingly (e.g. *TDocStd*, *PDocStd*, *MDocStd*).
+- Packages ending with <i>...Test</i> define Draw Harness plugins.
+- Methods starting with *Get...* and *Set...* are usually responsible for correspondingly retrieving and storing data.
 
 ### Related names
-Names that define logically connected functionality should have the same prefix (start with the same letters) or, at least, have any other common part in them.
-As an example the method GetCoord can be given. It returns a triple of real values and is defined for directions, vectors and points. The logical connection is obvious.

+Toolkit names are prefixed by *TK*, followed by a meaningful part of the name explaining the domain of functionality covered by the toolkit (e.g. *TKOpenGl*).
 
 ### Names of classes

+Usually the names of source files located in a unit start from the unit name separated from the other part of the file name by underscore "_".
 
-    <unit-name>_<class-name>.cxx (.hxx, .cdl etc.)

 ### Constants and inlines over defines [MANDATORY]
+
 Use constant variables (const) and inline functions instead of defines (#define).
 
 ### Avoid explicit numerical values [MANDATORY]
+
 Avoid usage of explicit numeric values. Use named constants and enumerations instead.
-Magic numbers are badly to read and maintain.
+Numbers produce difficulties for reading and maintenance.
 
 ### Three mandatory methods
-A class with any of (destructor, assignment operator, copy constructor) usually needs all of them.
+
+If a class has a destructor, an assignment operator or a copy constructor, it usually needs the other two methods.
 
 ### Virtual destructor
+
 A class with virtual function(s) ought to have a virtual destructor.
 
 ### Default parameter value
+
 Do not redefine a default parameter value in an inherited function.
 
 ### Use const modifier
-Use const modifier wherever possible (functions parameters, return values etc.)
+
+Use *const* modifier wherever possible (functions parameters, return values, etc.)
 
 ### Usage of goto [MANDATORY]
-Avoid goto statement except the cases where it is really needed.
+Avoid *goto* statement unless it is really needed.
 
 ### Declaring variable in for() header
-Declaring cycle variable in the header of the for() statement if not used out of cycle.

+### Provide code portability [MANDATORY]
+
+The source code must be portable to all platforms listed in the official 'Technical Requirements'.
 The term 'portable' here means 'able to be built from source'.
 
 The C++ source code should meet C++03 standard.
-Any usage of compiler-specific features or further language versions (C++11, until all major compliers on all supported platforms do not implement all it features)
-should be optional (escaped with appropriate preprocessor checks) and non-exclusive (alternative implementation should be provided, compatible with other compilers).

+Use global (package or class) functions that return reference to static variable local to this function instead of global variables.
+
 Another possible problem is the order of initialization of global variables defined in various libraries that may differ depending on platform, compiler and environment.
 
 ### Avoid explicit basic types
-Avoid explicit usage of basic types (int, float, double etc.), use Open CASCADE Technology types (from package Standard - see Standard_Integer, Standard_Real, Standard_ShortReal, Standard_Boolean, Standard_CString and others) or specific typedef instead.
 
-### Use sizeof() to calculate sizes [MANDATORY]
-Do not assume sizes of types. Use sizeof() instead to calculate sizes.
+Avoid explicit usage of basic types (*int*, *float*, *double*, etc.), use Open CASCADE Technology types from package *Standard: Standard_Integer, Standard_Real, Standard_ShortReal, Standard_Boolean, Standard_CString* and others or a specific *typedef* instead.

 The rules listed in this chapter are important for stability of the programs that use Open CASCADE Technology libraries.
 
-### OSD::SetSignal() to catch exceptions
-When using Open CASCADE Technology in an application, make sure to call OSD::SetSignal() function when the application is initialized.
-This will install C handlers for run-time interrupt signals and exceptions,
-so that low-level exceptions (such as access violation, division by zero etc.) will be redirected to C++ exceptions
-(that use try {...} catch (Standard_Failure) {...} blocks).
+### Use *OSD::SetSignal()* to catch exceptions
+
+When using Open CASCADE Technology in an application, call *OSD::SetSignal()* function when the application is initialized.

+This will install C handlers for run-time interrupt signals and exceptions, so that low-level exceptions (such as access violation, division by zero, etc.) will be redirected to C++ exceptions
+that use *try {...} catch (Standard_Failure) {...}* blocks.
+
 The above rule is especially important for robustness of modeling algorithms.

+
+### Validate the number of input parameters

+
+@section occt_debug_intro Introduction
+
+This manual describes facilities included in OCCT to support debugging, and provides some hints for more efficient debug.
+
+@section occt_debug_bop Self-diagnostics in Boolean operations algorithm
+
+In real-world applications modeling operations are often performed in a long sequence, while the user sees only the final result of the whole sequence. If the final result is wrong, the first debug step is to identify the offending operation to be debugged further. Boolean operation algorithm in OCCT provides a self-diagnostic feature which can help to do that step.
+
+This feature can be activated by defining environment variable *CSF_DEBUG_BOP*, which should specify an existing writeable directory.
+
+The diagnostic code checks validity of the input arguments and the result of each Boolean operation. When an invalid situation is detected, the report consisting of argument shapes and a DRAW script to reproduce the problematic operation is saved to the directory pointed by *CSF_DEBUG_BOP*.
+
+@section occt_debug_exceptions Calling JIT debugger on exception
+
+On Windows platform when using Visual Studio compiler there is a possibility to start the debugger automatically if an exception is caught in a program running OCCT. For this, set environment variable *CSF_DEBUG* to any value. Note that this feature works only if you enable OCCT exception handler in your application by calling *OSD::SetSignal()*.
+
+@section occt_debug_call Functions for calling from debugger
+
+Modern interactive debuggers provide the possibility to execute application code at a program break point. This feature can be used to analyse the temporary objects available only in the context of the debugged code. OCCT provides several global functions that can be used in this way.
+
+Note that all these functions accept pointer to variable as <i>void*</i> to allow calling the function even when debugger does not recognize type equivalence or can not perform necessary type cast automatically. It is responsibility of the developer to provide the correct pointer. In general these functions are not guaranteed to work, thus use them with caution and at your own risk.
+
+@subsection occt_debug_call_draw Interacting with DRAW
+
+Open CASCADE Test Harness or @ref user_guides__test_harness "DRAW" provides an extensive set of tools for inspection and analysis of OCCT shapes and geometric objects and is mostly used as environment for prototyping and debugging OCCT-based algorithms.
+
+In some cases the objects to be inspected are available in DRAW as results of DRAW commands. In other cases, however, it is necessary to inspect intermediate objects created by the debugged algorithm. To support this, DRAW provides a set of commands allowing the developer to store intermediate objects directly from the debugger stopped at some point during the program execution (usually at a breakpoint).
+
+~~~~~
+const char* Draw_Eval (const char *theCommandStr)
+~~~~~
+
+Evaluates a DRAW command or script.
+A command is passed as a string parameter.
+
+~~~~~
+const char* DBRep_Set (const char* theNameStr, void* theShapePtr)
+~~~~~
+
+Sets the specified shape as a value of DRAW interpreter variable with the given name.
+- *theNameStr* - the DRAW interpreter variable name to set.
+- *theShapePtr* - a pointer to *TopoDS_Shape* variable.
+
+~~~~~
+const char* DrawTrSurf_Set (const char* theNameStr, void* theHandlePtr)
+const char* DrawTrSurf_SetPnt (const char* theNameStr, void* thePntPtr)
+const char* DrawTrSurf_SetPnt2d (const char* theNameStr, void* thePnt2dPtr)
+~~~~~
+
+Sets the specified geometric object as a value of DRAW interpreter variable with the given name.
+- *theNameStr* - the DRAW interpreter variable name to set.
+- *theHandlePtr* - a pointer to the geometric variable (Handle to *Geom_Geometry* or *Geom2d_Curve* or descendant) to be set.
+- *thePntPtr* - a pointer to the variable of type *gp_Pnt* to be set.
+- *thePnt2dPtr* - a pointer to the variable of type *gp_Pnt2d* to be set.
+
+All these functions are defined in *TKDraw* toolkit and return a string indicating the result of execution.
+
+@subsection occt_debug_call_brep Saving and dumping shapes and geometric objects
+
+The following functions are provided by *TKBRep* toolkit and can be used from debugger prompt:
+
+~~~~~
+const char* BRepTools_Write (const char* theFileNameStr, void* theShapePtr)
+~~~~~
+
+Saves the specified shape to a file with the given name.
+- *theFileNameStr* - the DRAW interpreter variable name to set.
+- *theShapePtr* - a pointer to *TopoDS_Shape* variable.
+
+~~~~~
+const char* BRepTools_Dump (void* theShapePtr)
+const char* BRepTools_DumpLoc (void* theShapePtr)
+~~~~~
+
+Dumps shape or its location to cout.
+- *theShapePtr* - a pointer to *TopoDS_Shape* variable.
+
+The following additional function is provided by *TKGeomBase* toolkit:
+
+~~~~~
+const char* GeomTools_Dump (void* theHandlePtr)
+~~~~~
+
+Dump geometric object to cout.
+- *theHandlePtr* - a pointer to the geometric variable (<i>Handle</i> to *Geom_Geometry* or *Geom2d_Curve* or descendant) to be set.
+
+@section occt_debug_vstudio Using Visual Studio debugger 
+
+@subsection occt_debug_vstudio_command Command window 
+
+Visual Studio debugger provides the Command Window (can be activated from menu <b>View / Other Windows / Command Window</b>), which can be used to evaluate variables and expressions interactively in a debug session (see http://msdn.microsoft.com/en-us/library/c785s0kz.aspx). Note that the Immediate Window can also be used but it has some limitations, e.g. does not support aliases.
+
+When the execution is interrupted by a breakpoint, you can use this window to call the above described functions in context of the currently debugged function. Note that in most cases you will need to specify explicitly context of the function by indicating the name of the DLL where it is defined.
+
+For example, assume that you are debugging a function, where local variable *TopoDS_Edge* *anEdge1* is of interest.
+The following set of commands in the Command window will save this edge to file *edge1.brep*, then put it to DRAW variable *e1* and show it maximized in the axonometric DRAW view:
+
+~~~~~
+>? ({,,TKBRep.dll}BRepTools_Write)("d:/edge1.brep",(void*)&anEdge1)
+0x04a2f234 "d:/edge1.brep"
+>? ({,,TKDraw.dll}DBRep_Set)("e1",(void*)&anEdge1)
+0x0369eba8 "e1"
+>? ({,,TKDraw.dll}Draw_Eval)("donly e1; axo; fit")
+0x029a48f0 ""
+~~~~~
+
+For convenience it is possible to define aliases to commands in this window, for instance (here ">" is prompt provided by the command window; in the Immediate window this symbol should be entered manually):
+
+~~~~~
+>alias deval      ? ({,,TKDraw}Draw_Eval)
+>alias dsetshape  ? ({,,TKDraw}DBRep_Set)
+>alias dsetgeom   ? ({,,TKDraw}DrawTrSurf_SetPnt)
+>alias dsetpnt2d  ? ({,,TKDraw}DrawTrSurf_SetPnt2d)
+>alias saveshape  ? ({,,TKBRep}BRepTools_Write)
+>alias dumpshape  ? ({,,TKBRep}BRepTools_Dump)
+>alias dumploc    ? ({,,TKBRep}BRepTools_DumpLoc)
+>alias dumpgeom   ? ({,,TKGeomBase}GeomTools_Dump)
+~~~~~ 
+
+Note that aliases are stored in the Visual Studio user's preferences and it is sufficient to define them once on a workstation. With these aliases, the above example can be reproduced easier (note the space symbol after alias name!):
+
+~~~~~
+>saveshape ("d:/edge1.brep",(void*)&anEdge1)
+0x04a2f234 "d:/edge1.brep"
+>dsetshape ("e1",(void*)&anEdge1)
+0x0369eba8 "e1"
+>deval ("donly e1; axo; fit")
+0x029a48f0 ""
+~~~~~
+
+Note that there is no guarantee that the call will succeed and will not affect the program execution, thus use this feature at your own risk. In particular, the commands interacting with window system (such as *axo*, *vinit*, etc.) are known to cause application crash when the program is built in 64-bit mode. To avoid this, it is recommended to prepare all necessary view windows in advance, and arrange these windows to avoid overlapping with the Visual Studio window, to ensure that they are visible during debug. 
+
+@subsection occt_debug_vstudio_watch Customized display of variables content
+
+Visual Studio provides a way to customize display of variables of different types in debugger windows (Watch, Autos, Locals, etc.).
+
+In Visual Studio 2005-2010 the rules for this display are defined in file *autoexp.dat* located in  subfolder *Common7\\Packages\\Debugger* of the Visual Studio installation folder (hint: the path to that folder is given in the corresponding environment variable, e.g. *VS100COMNTOOLS* for vc10). This file contains two sections: *AutoExpand* and *Visualizer*. The following rules can be added to these sections to provide more convenient display of some OCCT data types.

+This document provides practical guidelines for generation and editing of OCCT user documentation.
 
 @section  OCCT_DM_SECTION_2 Prerequisites
 
-<b>Tcl/Tk</b>
+You need to have the following software installed to generate the documentation.
+
+**Tcl/Tk**
 Version 8.5 or 8.6: http://www.tcl.tk/software/tcltk/download.html
 
-<b>Doxygen</b> 
+**Doxygen**
 Version 1.8.4 or above: http://www.stack.nl/~dimitri/doxygen/download.html
 
-<b>MathJax</b> (used for rendering math formulas in browser). 
-See \ref OCCT_DM_SECTION_A_9 paragraph for more detailed description. 
-The latest version: http://www.mathjax.org/download/
+**MiKTeX** or other package providing **pdflatex** command (only needed for generation of PDF documents): http://miktex.org/download
 
-<b>MiKTeX</b> or equivalent tool (used for PDF document creation)
+**Inkscape** (only needed for generation of PDF documents containing SVG images): http://www.inkscape.org/download
 
-Latest version: http://miktex.org/download
+When generating PDF documentation, **pdflatex** and **inkscape** executables should be accessible by PATH variable.
+You can use *custom.bat* file to add necessary paths to the *PATH* variable. 
 
-**Note**: to generate pdf documentation with MiKTeX you should execute gendoc.bat within MiKTeX environment 
-(run gendoc.bat in MiKTeX command promt or update PATH for MiKTeX bin folder). Also in process of pdf generation
-MiKTeX can request you to download missing packages if MiKTeX was installed with option below:
+Note that in the process of PDF generation MiKTeX may need some packages not installed by default.
+We recommend setting option "Install missing packages on-the-fly" to "Ask me first" (default) during MiKTeX installation:
 
-@image html /dev_guides/documentation/images/documentation_image002.png
-@image latex /dev_guides/documentation/images/documentation_image002.png
+@figure{/dev_guides/documentation/images/documentation_miktex.png}
 
-If this option is set to "Yes", MiKTeX will download missing packages automatically.
+On the first run of **pdflatex** it will open a dialog window prompting for installation of missing packages.
+Follow the instructions to proceed (define proxy settings if needed, select a mirror site to download from, etc.).
+
+**MathJax** is used for rendering math formulas in browser (HTML and CHM outputs): http://www.mathjax.org.
+
+By default MathJAX scripts and fonts are taken from http://cdn.mathjax.org/mathjax/latest and no installation of MathJAX is necessary if Internet is accessible.
+If you need to use OCCT documentation while off-line, you can install a local copy of MatJAX, see http://www.mathjax.org/download/.
+See \ref OCCT_DM_SECTION_A_9 for more details on inserting mathematical expressions.

-*/dox/dev_guides/svn/ - for svn.md file
-*/dox/dev_guides/svn/images/ - for images
+Place a new document in the folder taking into account its logical position in the documentation hierarchy. For instance, the document *svn.md* about the use of SVN to work with OCCT source code can be placed into <i>/dox/dev_guides/</i>. 
+
+If there are images in the document, it should be placed in its own folder containing a subfolder for images. For instance:
+* <i> /dox/dev_guides/svn/ </i> - for *svn.md* file;
+* <i> /dox/dev_guides/svn/images/ </i> - for images.
+
+Add a relative path to *svn.md* in file <i>dox/FILES.txt</i>. For instance
 
- - Update dox/FILES.txt to add relative path to svn.md. For instance

+* <i>\@section</i> - for the first-level headers; 
+* <i>\@subsection</i> - for the second level headers;
+* <i>\@subsubsection</i> - for the third level headers.

+Please, note that section names can be used for references within the document and in other documents, so it is necessary to use the common prefix indicative of the document name for all section names in the given document. 
+For example,  *occt_ocaf* for sections in Open CASCADE Application Framework manual.
 
-Header 2
----------
+The remaining part of section names in most documents consists only of numbers, for example *1_1*. Actually, the hierarchical structure of the output table of contents is not based on these numbers and is generated automatically. 
 
-Where a word in curly braces is a MarkDown-style reference, which can be used in table of contents.
-If you would like to have the table of contents, it is recommended to use \@section,

-  @subsubsection SubSubSection_Name SubSubSection Header
-@endverbatim
+If you insert a section in the middle of a big document, do not renumber the document to the end (which is inefficient and error prone), but choose an arbitrary number or letter, not yet used in the document section naming, and base the naming in this section on it.
+
+The section hierarchy is limited to three levels and further levels cannot be presented in the Table of Contents.
+
+However, the fourth and fifth level headers can be tagged with  <i>####</i> and <i>#####</i> correspondingly.

-To emphasize some words, write one pair of asterisks ( * ) or underscores ( _ ) across the word

+Smaller code blocks can be inserted by wrapping with tags <i>\@code</i> and <i>\@endcode</i>.
 
+Verbatim content (same as code but without syntax highlighting) can be inserted by wrapping with tags <i>\@verbatim</i> and <i>\@endverbatim</i>.
 
 @subsection  OCCT_DM_SECTION_A_6 References
 
-To insert a reference to a website, it is proposed to write a URL. For example: http://en.wikipedia.org
-To insert a reference to another part of the same document, the developer can write:
+To insert a reference to a website, it is sufficient to write an URL.
+For example: http://en.wikipedia.org
 
-@verbatim
-  @htmlonly 
-    <a href="#OCCT_DOC_SECTION_5">Doxygen Configuration file</a>
-  @endhtmlonly 
-@endverbatim
+To insert a reference to a document or its subsection, use command <i>\@ref</i> followed by the document or section tag name.
+For instance, @code @ref OCCT_DM_SECTION_A @endcode will be rendered as @ref OCCT_DM_SECTION_A.
 
-to get a link to paragraph : @htmlonly <a href="#OCCT_DOC_SECTION_5">Doxygen configuration</a> @endhtmlonly 
+Note that links between documents will not work in PDF output if each document is generated independently.
+Hence it is recommended to add a name of the referenced section after the tag name in the <i>\@ref</i> command (in quotes): this will guarantee that the reference is recognizable for the reader even if the cross-link is not instantiated. 
+For instance: @code @ref occt_modat_1 "Geometry Utilities" @endcode will be rendered as @ref occt_modat_1 "Geometry Utilities".
 
 @subsection  OCCT_DM_SECTION_A_7 Images
 
-To insert image into document the developer can write the following code(in Doxygen-style):
+For inserting images into the document use the command <i>\@figure</i>, as follows:
 
-For HTML document:
 @verbatim
-  @image html /relative/path/to/image/image001.png "Image caption"
+  @figure{/relative/path/to/image/image_file_name.png,"Image caption"}
 @endverbatim
 
-For latex document:
+The first argument is a path to the image file, relative to the *dox* folder.
+The supported formats for images are PNG, JPG, and SVG.
+The file extension must be lowercase and correspond to the file format.
+The image file name should have no dots except for the one before extension (names with more than one dot confuse **pdflatex**).
+
+The second argument is optional, it defines the caption for the image to be inserted.
+The caption argument, if given, should be quoted, even if it is a single word.
+Captions are included below the image; in PDF output the images with caption are numbered automatically.
+
+Example:
+
 @verbatim
-  @image latex /relative/path/to/image/image001.png "Image caption"
+  @figure{/dev_guides/documentation/images/documentation_test_image.svg,"Test SVG image"}
 @endverbatim
 
-*Note*: When markdown document is used to generate html document the latex insertion is ignored (and vice versa) 
-due to this fact you can use image insertions in the pair, like example below:
+is rendered as:
+
+@figure{/dev_guides/documentation/images/documentation_test_image.svg,"Test SVG image"}
+
+We recommend using **Inkscape** for creation and edition of vector graphics.
+The graphics created in MS Word Draw and some other vector editors can be copy-pasted to Inkscape and saved as SVG images.
+
+Note that the image that will be included in documentation is the whole page of the Inkscape document; use option "Resize page to content" in menu **File -> Document properties** of Inkscape to fit page dimensions to the picture (adding margins as necessary).
+
+Note that the *figure* command is an alias to the standard Doxygen command *image* repeated twice: once for HTML and then for Latex output (used for PDF generation). Thus if HTML and PDF outputs should include different images or captions, command "image" can be used:
+
 @verbatim
-  @image html /relative/path/to/image/image001.png "Image caption"
-  @image latex /relative/path/to/image/image001.png "Image caption"
+  @image html /relative/path/to/image/occ_logo.png
+  @image latex /relative/path/to/image/occ_logo.png "OCC logo"
 @endverbatim
 
-The code below tells Doxygen to insert a picture right in the place this code was written:
-@verbatim
-  @image html /resources/occ_logo.png "OCCT logo"
-  @image latex /resources/occ_logo.png "OCCT logo"
-@endverbatim
-
-@image html /resources/occ_logo.png "OCCT logo"
-@image latex /resources/occ_logo.png "OCCT logo"
+@image html /resources/occ_logo.png
+@image latex /resources/occ_logo.png "OCC logo"
  
 @subsection  OCCT_DM_SECTION_A_8 Table Of Contents
 
-To get the table of contents at the beginning of the document, write \@tableofcontents tag. 
-But it is not needed now because TreeView option for HTML is used.
+Use \@tableofcontents tag to get the table of contents at the beginning of the document. 
+  
+Actually, it is not strictly necessary now because TreeView option for HTML is used.
 The TOC in the PDF document will be generated automatically.
 
 @subsection  OCCT_DM_SECTION_A_9 Formulas
 
-Formulas within documents will be generated using MathJax tool.
-
-A developer has to specify these parameters in Doxyfile to enable support of MathJax in Doxygen:
-
-    USE_MATHJAX         = YES
-    MATHJAX_FORMAT      = HTML-CSS
-    MATHJAX_RELPATH     = http://cdn.mathjax.org/mathjax/latest
-    MATHJAX_EXTENSIONS  = TeX/AMSmath TeX/AMSsymbols
-
-To use MathJax tool with the HTML page, it's \<head\> block has to contain 
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.html}
-    <script type="text/x-mathjax-config">
-      MathJax.Hub.Config({
-        tex2jax: {inlineMath: [["$","$"],["\\(","\\)"]]},
-        displayAlign: "left"
-      });
-    </script>

-      src="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML">
-    </script>
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-First script configures MathJax to understand separator types and to left allign formulas. 
-The second script inserts reference to MathJax tool. 
-This tool will always be used when the HTML output will be shown.
+Formulas within MarkDown documents can be defined using LaTeX syntax.
