  17 // The following part of the code determines the CLIENT_BUILD variable.
  18 // Several mechanisms are used for this:
  19 // * first, if HAVE_BUILD_INFO is defined, include build.h, a file that is
  20 //   generated by the build environment, possibly containing the output
  21 //   of git-describe in a macro called BUILD_DESC
  22 // * secondly, if this is an exported version of the code, GIT_ARCHIVE will
  23 //   be defined (automatically using the export-subst git attribute), and
  24 //   GIT_COMMIT will contain the commit id.
  25 // * then, three options exist for determining CLIENT_BUILD:
  26 //   * if BUILD_DESC is defined, use that literally (output of git-describe)
  27 //   * if not, but GIT_COMMIT is defined, use v[maj].[min].[rev].[build]-g[commit]
  28 //   * otherwise, use v[maj].[min].[rev].[build]-unk
  29 // finally CLIENT_VERSION_SUFFIX is added
