# 20210802 bkw: update for v2.2
# - remove texi2html dep, as upstream now uses texi2any
# - related to above, always build the HTML docs
# - add flite_time and t2p to usr/bin. Also man pages for same,
#   from Debian.
# - Note to self: the shared library versioning is weird looking. The
#   soname version is 1, same as FLITE_PROJECT_SHLIB_VERSION
#   in flite_version.h, and the files are installed as
#   libfliteblah.2.2. So we end up with symlinks libfliteblah.so.1 =>
#   libfliteblah.2.2, which is actually correct.

# 20181114 bkw:
# - BUILD=2
# - add WTFPL to script
# - always build the .info API docs
# - get rid of DOCS env variable
# - only build HTML docs if texi2html is available
# - update README to document the above
# - minor updates to man page and slack-desc
# - add HTML=no to skip building HTML docs

# 20180612 bkw: update for 2.1 (or is it 2.1.0?)

# 20170614 bkw:
# - add ldflags patch from King Beowulf, to allow external programs
#   to link correctly with libflite.so. BUILD=2.

# 20150623 bkw:
# - fix doc build failure with standalone SBo texi2html, thanks
#   to John Vogel for investigating this
# - add DOCS=no option, in case a future texi2html has more
#   issues

# 20150509 bkw:
# - update for 2.0.0
# - add HTML and .info docs
# - add man page
# - update HOMEPAGE
# - add optional extra voice support

# 20141020 bkw: fix handy-ruler, make VERSION respect environment.

# 20130411 bkw: Updated for flite 1.4, added fix for parallel builds.
# Removed --with-vox=cmu_us_kal16 configure flag (it doesn't seem to
# do anything).
# The updated version is released under the WTFPL, see
# http://www.wtfpl.net/txt/copying/ for details.
