  22 ## This target generates an include file that contains the git version
  23 ## string of the current branch, it must be continuously updated when
  24 ## we build in the git repo and shipped in dist tarballs to reflect the
  25 ## status of the tree when it was generated. If the tree is clean and
  26 ## the current commit is tag a starting with "v", consider this a
  27 ## release version and set an empty git version.
  28 ##
  29 ## Here is what the inline script does:
  30 ##
  31 ## First, delete any stale "version.i.tmp" file.
  32 ##
  33 ## If "bootstrap" and ".git" exists in the top source directory and the git
  34 ## executable is available, get the current git version string in the form:
  35 ##
  36 ##  "latest_tag"(-"number_of_commits_on_top")(-g"latest_commit_hash")(-dirty)
  37 ##
  38 ## And store it in "version.i.tmp", if the current commit is tagged, the tag
  39 ## starts with "v" and the tree is clean, consider this a release version and
  40 ## overwrite the git version with an empty string in "version.i.tmp".
  41 ##
  42 ## If we don't have a "version.i.tmp" nor a "version.i", generate an empty
  43 ## string as a failover.
  44 ##
  45 ## If we don't have a "version.i" or we have both files and they are different,
  46 ## copy "version.i.tmp" over "version.i". This way the dependent targets are
  47 ## only rebuilt when the version string changes.
