#  Modified for 0.9.3a by Jeremy Hansen <jebrhansen+SBo -at- gmail.com>

# 20220211 bkw: BUILD=4.
# - fix build on 15.0 (PyYAML issue).
# - lirc doesn't ship a kernel module any more, so get rid of the
#   KERNEL variable and don't put the kernel version in the package's
#   version.
# - install usable HTML conversions of the man pages (instead of
#   identical broken ones).
# - considered upgrading to 0.10.1 (latest release), but it still has
#   the same problems (HTML man conversions and PyYAML), and I don't have
#   any IR hardware to test this with, so I'll leave it at the (presumably)
#   maintainer-tested version 0.9.3a.

# 20211121 bkw: BUILD=3. install all docs to
# /usr/doc/$PRGNAM-$VERSION, instead of /usr/share/doc/$PRGNAM. Also
# don't include useless INSTALL in doc dir.

# 20220211 bkw: Source ships with HTML conversions of man pages, but
# make thinks it needs to regenerate them. Touching them doesn't help,
# it always tries to convert them regardless of timestamps. And the
# conversion fails, because our man2html (from man-db) doesn't support
# the -M and -r options. It doesn't stop the Makefile from finishing,
# but all the html pages end up broken/useless. The configure script
# reads an environment variable MAN2HTML, which... does nothing. We
# can't even copy them, let make overwrite them, and restore the
# originals, because 'make install' will regenerate them again.

# So save the originals, let 'make install' generate and install the
# broken ones, then copy the originals to $PKG/usr/doc afterwards.
