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