-# The following section is based on a similar feature in LTTng-tools.

## 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 a "version.i" is present, for example when building
-## from a distribution tarball, get the git_version using grep.
-##
-## Fetch the BT_VERSION_EXTRA_NAME define from "version/extra_version_name" and output it
-## to "version.i.tmp".
-##
-## Fetch the BT_VERSION_EXTRA_DESCRIPTION define from "version/extra_version_description",
-## sanitize and format it with a sed script to replace all non-alpha-numeric values
-## with "-" and join all lines by replacing "\n" with litteral string c-style "\n" and
-## output it to "version.i.tmp".
-##
-## Repeat the same logic for the "version/extra_patches" directory.
-## Data fetched from "version/extra_patches" must be sanitized and
-## formatted.
-## The data is fetched using "ls" with an ignore pattern for the README.adoc file.
-## The sanitize step uses sed with a script to replace all
-## non-alpha-numeric values, except " " (space), to "-".
-## The formatting step uses sed with a script to join all lines
-## by replacing "\n" with litteral string c-style "\n".
-##
-## If we don't have a "version.i" or we have both files (version.i, version.i.tmp)
-## and they are different, copy "version.i.tmp" over "version.i".
-## This way the dependent targets are only rebuilt when the git version
-## string or either one of extra version string change.
