# 20260908 bkw: libtorrent used to be a separate build. Nothing but
# rtorrent ever used it, and we also have two versions of the
# similarly-named (but utterly different) libtorrent-rasterbar
# (one of which is called "libtorrent2"). De-confused the issue
# by merging libtorrent and rtorrent.
# The libtorrent installed with this package does NOT conflict
# with libtorrent-rasterbar (or libtorrent2).

# First, the library. Doesn't ship a configure script, generate it.
