23 #    Inspects a given file for the following expressions
24 #    "NAME_VERSION_MAJOR #"
25 #    "NAME_VERSION_MINOR #"
26 #    "NAME_VERSION_PATCH #"
27 #    and sets NAME_VERSION accordingly. NAME_PART_VERSION variables are also
28 #    set. If you wish to look for different parts (e.g. "first" "second", etc.)
29 #    simply deliver them as additional arguments (have to be three though).
