#	Shell script to create a MacOS X package of the library.
#	The package will hold an end-user version of Allegro,
#	installing just the system wide library framework.
#	The created package is compatible with MacOS X 10.2 and newer.
#
#	Thanks to macosxhints.com for the hint!
#
#	Usage: mkpkg <allegro_dir>
#
#	Will create a package in the current directory; allegro_dir
#	must be a valid Allegro directory structure, holding the
#	previously compiled MacOS X dynamic library.
