#
# GIT-HEAD helper
# The file ./src/githead.h contains a constant BUILD_GIT_HEAD which is defined
# to the string returned by "git describe". We need to adjust this string for
# every build and correctly rebuild any sources that depend on it. Therefore,
# you should use this file rarely as it causes rebuilds on every git-commit.
#
# We have a helper-script ./src/genversion.sh that takes as argument the header
# file and creates it if necessary. It updates it only if the new git-describe
# string is different to the old one. So the file is only modified on changes.
# Hence, we can use it as normal dependency in this Makefile.
# However, we need to run this script on _every_ "make" invocation before any
# recipy is executed. To achieve this, we use $(shell ...) and assign it to a
# "simply expanded" variable (:=) so the shell command is executed on
# variable-declaration and not during expansion.
#
# Note that we must not clean ./src/githead.h ever! If we would, a distribution
# tarball might delete that file and have no way to recreate it.
# We could delete it on something like "make maintainerclean", but then again,
# it seems unnecessary so lets simply not clean it at all.
#
# If the helper-script is executed in a directory that is not a git-repository
# (like a distribution tarball) and githead.h exists, then it does nothing as it
# expects githead.h to be correctly written by "make dist".
# However, if githead.h does not exist, it will print a warning and write
# "<unknown>" as git-revision.
# This guarantees, that githead.h is always present and has the most correct
# value that we can get under any conditions.
#
# The $(emptyvariable) expansion below is used for broken $(shell ...)
# syntax-highlighting algorithms in many existing editors.
