NAME:
  $CmdName - check ABI compatibility of shared C/C++ library versions

DESCRIPTION:
  Lightweight tool for statically checking backward binary compatibility of shared C/C++ libraries
  in Linux. It checks header files along with shared objects in two library versions and searches
  for ABI changes that may lead to incompatibility. Breakage of the binary compatibility may result
  in crashing or incorrect behavior of applications built with an old version of a library when
  it is running with a new one.

  ABI Compliance Checker was intended for library developers that are interested in ensuring
  backward binary compatibility. Also it can be used for checking forward binary compatibility
  and checking applications portability to the new library version.
  
  This tool is free software: you can redistribute it and/or modify it under the terms of the GNU GPL.

USAGE:
  $CmdName [options]

EXAMPLE OF USE:
  $CmdName -l &lt;library_name&gt; -d1 &lt;1st_version_descriptor&gt; -d2 &lt;2nd_version_descriptor&gt;

GENERAL OPTIONS:
  -h|-help
      Print this help.

  -v|-version
      Print version.

  -l|-library &lt;name&gt;
      Library name (without version).
      It affects only on the path and the title of the report.

  -d1|-descriptor1 &lt;path&gt;
      Path to descriptor of 1st library version.

  -d2|-descriptor2 &lt;path&gt;
      Path to descriptor of 2nd library version.

EXTRA OPTIONS:
  -app|-application &lt;path&gt;
      This option allow to specify the application that should be tested for portability
      to the new library version.

  -dump_abi|-dump_info &lt;descriptor_path&gt;
      Dump library ABI information using specified descriptor.
      This command will create '&lt;library&gt;_&lt;ver1&gt;.abi.tar.gz' file in the directory 'abi_dumps/&lt;library&gt;/'.
      You can transfer it anywhere and pass instead of library descriptor.

  -headers_only
      Check header files without shared objects. It is easy to run, but may provide
      a low quality ABI compliance report with false positives and without
      detecting of added/withdrawn interfaces.

  -symbols_list|-int_list &lt;path&gt;
      This option allow to specify a file with a list of interfaces (mangled names in C++)
      that should be checked, other library interfaces will not be checked.

OTHER OPTIONS:
  -d|-descriptor_template
      Create library descriptor template 'library-descriptor.xml' in the current directory.

  -separately
      Check headers individually. This mode requires more time for checking ABI compliance,
      but possible compiler errors in one header can't affect others.

  -test
      Run internal tests (create two binary-incompatible versions of an artificial library
      and run ABI-Compliance-Checker on it).

DESCRIPTOR EXAMPLE:
  &lt;version&gt;
     1.28.0
  &lt;/version&gt;

  &lt;headers&gt;
     /usr/local/atk/atk-1.28.0/include/
  &lt;/headers&gt;

  &lt;libs&gt;
     /usr/local/atk/atk-1.28.0/lib/libatk-1.0.so
  &lt;/libs&gt;

  &lt;include_paths&gt;
     /usr/include/glib-2.0/
     /usr/lib/glib-2.0/include/
  &lt;/include_paths&gt;
