# 20220307 bkw: this is a rename and rework of the old SBo
# gst-plugins-bad. Here we build only the portions of gst-plugins-bad
# that are missing from Slackware's gst-plugins-bad-free. Despite
# the -nonfree in the name, not all of these are encumbered (some
# just aren't included in Slackware because it lacks the optional
# dependencies).

# So we build it, then remove it from $PKG after it's installed.
