  40 // Several mechanisms are used for this:
  41 // * first, if HAVE_BUILD_INFO is defined, include build.h, a file that is
  42 //   generated by the build environment, possibly containing the output
  43 //   of git-describe in a macro called BUILD_DESC
  44 // * secondly, if this is an exported version of the code, GIT_ARCHIVE will
  45 //   be defined (automatically using the export-subst git attribute), and
  46 //   GIT_COMMIT will contain the commit id.
  47 // * then, three options exist for determining CLIENT_BUILD:
  48 //   * if BUILD_DESC is defined, use that literally (output of git-describe)
  49 //   * if not, but GIT_COMMIT is defined, use v[maj].[min].[rev].[build]-g[commit]
  50 //   * otherwise, use v[maj].[min].[rev].[build]-unk
