# Slackware build script for fountain

# Notes:

# I can't find an actual content-bearing homepage for this. It's a
# very useful utility, so I packaged it up with a placeholder homepage.

# The support library tracefct is just built statically and linked into
# the executable. If ever there's a need for it, it could be broken out
# into its own SlackBuild easily enough.

# No idea why the man page is installed in section "l". I never heard
# of this before. Wikipedia lists it as "LAPACK library functions",
# which this most certainly isn't. So I moved it to section 1.

# who ever heard of man section "l"? horrible idea anyway (looks too
# much like a 1 in most fonts). the "right" way to fix this would
# be to sed docs/Makefile.am, but this project is too old for modern
# autotools to work with, so post hoc hackery is called for. While
# we're at it, fix some grammar and readability issues.
