# Build and install GNU emacs for Slackware.
# Before starting, you might want to reduce dependancies in the
# .tgz packages by doing this (no, you really don't want to do this):
#                              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
#removepkg xaw3d
#rm /usr/lib/libjpeg.so
#rm /usr/lib/libpng.so
#rm /usr/lib/libtiff.so
#rm /usr/lib/libungif.so
# and then replace these things after the build.
