# 20201122 bkw: Grr. Forgot to git add the diffs.
# 20201119 bkw: modified by SlackBuilds.org:
# - BUILD=2.
# - Fix fltk builds.
# - Shut up a compiler warning.
# - Restore original homepage/download, since the site is back up.
# - Fix README to comply with 72-column limit.
# - Fix doubleplus ungood refs undirectory /usr/share/doc in man page.
# - Since the man page says there's a manual, actually install the
#   manual as part of the package. To avoid a dependency on lyx (and
#   consequently qt5!), pull the prebuilt docs out of upstream's
#   binary package.
