# supplies all of the necessary OSKit libraries (of which
# there are many all of which have odd ordering dependencies).

# The --oskit=* option is set by the oskit-configure shell script.
#
# XXX could use a --bootloader=foo option
#

# the OSKit install directory

# the proper  oskit_<OS>_m library
