/*! \file
 * \brief
 * Version information for software that links to \Gromacs.
 *
 * \if libapi
 * This include file will be configured by CMake and contains version
 * information.  It is not used by \Gromacs, but intended for software that
 * links to \Gromacs.
 * The values come from the main CMakeLists.txt.
 * \endif
 *
 * This file exists from 4.6 onward, and can be included as
 * `<gromacs/version.h>`.  In 4.6, it is also included by
 * `<gromacs/typedefs.h>, but that header has already moved in 5.0.
 *
 * This header defines two values, the \Gromacs version, and the API version.
 * The versions are in numerical form, where, for example, version
 * 4.6.1 would be 40601.
 *
 * The API version is defined in ::GMX_API_VERSION, and denotes the
 * version of the programmer interface, i.e. the installed header files
 * and compatible library.
 *
 * Programs written against the \Gromacs library can use this file
 * to provide some backward compatibility even though parts of the API
 * change.  For example:
 * \code
   #include <gromacs/version.h>
   #if (GMX_API_VERSION < 50000)
       .... <do pre-5.0 stuff>
   #else
       .... <do post-5.0 stuff>
   #endif
   \endcode
 * where version.h is included directly. For code that must be compatible
 * between 4.5 and 4.6, an interim solution is to include typedefs.h, which
 * includes this file:
 * \code
   #include <gromacs/typedefs.h>
   #if !defined(GMX_API_VERSION) || (GMX_API_VERSION < 40600)
       ....  <do 4.5 specific stuff>
   #elif (GMX_API_VERSION < 40700)
       ....  <do 4.6 specific stuff>
   #endif
   \endcode
 *
 * \inpublicapi

/*! \brief
 * API version of this set of \Gromacs headers.
 *
 * If there are multiple versions of \Gromacs that work with the same set of
 * headers, then this version is not updated between the versions, even though
 * ::GMX_VERSION is.
 * For 4.6 and 5.0 (and likely for some time in the future as well), this
 * tracks the exact \Gromacs version.
