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