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