23 #    Inspects a given file for the following expressions
24 #    "NAME_MAJOR_VERSION #"
25 #    "NAME_MINOR_VERSION #"
26 #    "NAME_PATCH_VERSION #"
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).
