# List of the directories that contain Fortran source.  Simply copying
# a new .f file into one of these directories is sufficient to have it
# added to $(LIBPRE)cruft.a.  If you add a new directory here, you also need
# generate a new configure script in the top-level directory (edit
# configure.in and run autoconf).

# Some of the directories in libcruft may be only optionally built,
# e.g. if they are already present on the system.  For these, their
# dirname is substituted by configure and may be the empty string.
