#   *	Building the automatically generated files for the release.

#   *	"Cleaning up" the file tree.

# These things will probably need to be changed with each CD release
# or whenever the host system changes configuration.

# Build the DirList, FileList and CRCList files.  Note that we ensure
# that a FileList and CRCList file exist by touching them before building
# the updated FileList, and then removing the CRCList file (even a
# previously existing one) after building the new FileList, since the
# CRCList needs to be rebuilt anyway if the FileList is touched.  However
# since we can't compute a CRC for the CRC file itself without major
# trickery, the CRCList is generated using a copy of FileList that has
# had the CRCList line removed.  All these gyrations ensure that the
# FileList file includes entries for both itself and the CRCList file,
# while the CRCList file contains no entry for itself.
#
# Also note that the output is stored in a temporary file on a different
# volume, so as to avoid problems on the Amiga with "find" trying to
# lock CRCList while it is open for write.
