# DIRTY HACK ALERT:
# -current's linuxdoc-tools hates upstream's sgml docs, and it's not
# obvious what's wrong (bug/regression in linuxdoc-tools? 14.2's worked
# fine). I'm not interested in trying to fix the problem because I
# fucking hate XML, and I especially hate the mess that's the Slackware
# linuxdoc-tools (28 source tarballs, interdependent). So I'll just
# include pre-generated (on 14.2) HTML docs in my self-hosted source
# tarball.
