#ifndef _gmx_version_h

/* This include file will be configured by CMake and contains version
   information, primarily for software that links to Gromacs.

   This file exists from 4.6 onward. In 4.6, it is #included in
   include/typedefs.h, but that is not guaranteed to be the case in later
   versions.

   The versions are in numerical form, where, for example, version
   4.6.1 would be 40601.
   The values come from the main CMakeLists.txt.

   This header defines two values, the Gromacs version, and the API version.

   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:

#include <gromacs/version.h>
#if (GMX_API_VERSION < 50000)
    .... <do pre-5.0 stuff>
#else
    .... <do post-5.0 stuff>
#endif

    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:

#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

   */
#define GMX_API_VERSION @API_VERSION@


/* GMX_VERSION contains the version number of the actual Gromacs library 
   and the Gromacs programs, in numerical format.

   As of 4.6, the Gromacs and API versions are the same, but this is not
   guaranteed to be the case in the future. */
