# Slackware build script for tribler

# Notes:

# The squelch_dht_exceptions patch is my own. I'm not a Python expert so if
# you've got a better solution, please let me know.

# Python dependency hell. Of the stuff in REQUIRES=, only gmpy could be
# optional. However if it's not installed, the application complains about it,
# and says upstream doesn't actually test their fallback code much.

# I didn't list vlc as a required dep, because without vlc installed, tribler
# is still a perfectly usable search engine and torrent client. Also vlc
# can be installed later and will work (it's a runtime dep).

# Don't be put off by the use of a tarball made from a git checkout. The
# release zipfile on upstream's site is incomplete (is missing the dispersy/
# subdirectory, for one thing). My source is from their v6.4.0 git tag, not
# from HEAD. See git2tarxz.sh.
