   3 # Simple utility script to generate the basic info
   4 # needed in a .pc (pkg-config) file, used especially
   5 # for introspection purposes
   6
   7 # This can be used in various projects where
   8 # there is the need to generate .pc files,
   9 # and is copied from GLib's $(srcroot)/win32
