LPAC is a codec (coder / decoder) for lossless compression of digital audio
files. "Lossless" means that any compressed file can be decompressed in a way
it will be bit-wise identical with the original. This is the main advantage
of LPAC compared to lossy formats like MP3, WMA or RealAudio. On the other
hand, lossy codecs can achieve higher compression ratios. For example, MP3 at
128 kbit/s achieves a (fixed) compression ratio of 11, whereas LPAC's
compression ratios range from 1.5 to 4, strongly depending on the audio
material. Typically they are around 2 for pop music and 2.5 for classical
music. This may not seem much, but remember you will get back every single
bit, no matter how often you subsequently compress and decompress a file. It
is true that general archivers (Zip, LZH, gzip) are lossless, too, but they
often achieve nearly no compression on audio files.
cleanup: Remove expired ports:
2021-10-31 devel/sdl_sge: Upstream no longer maintained
2021-12-31 net/appkonference: Outdated, depends on unsupported version of
net/asterisk
2021-12-31 dns/bind911: End of life, please migrate to a newer version of BIND9
2021-12-31 net/zebra: Abandoned upstream, last release in 2005. Consider
migrating to net/frr7 or net/bird2
2021-12-31 audio/osalp: Abandoned upstream, listed as beta and no new release
since 2008
2021-12-31 games/stransball2: Depends on expired devel/sdl_sge
2021-12-31 devel/rubygem-ruby-sdl-ffi: Depends on expired devel/sdl_sge
2021-12-31 devel/rubygem-rubygame: Depends on expired devel/sdl_sge
2021-12-31 devel/ruby-sdl: Depends on expired devel/sdl_sge
2021-12-31 games/magicmaze: Depends on expired devel/sdl_sge
2021-12-31 games/trophy: Depends on expired devel/clanlib1
2021-12-31 devel/clanlib1: Older than expired and removed devel/clanlib
2021-12-31 www/py-django31: Upgrade to Django 3.2+. Mainstream support ended
(April 6, 2021). Extended support ends December 2021. See

- Replace Mk/bsd.linux-apps.mk and Mk/bsd.linux-rpm.mk with
Mk/Uses/linux.mk.
- Replace USE_LINUX=yes with USES+=linux and USE_LINUX=(.*) with
USES+=linux:\1 in all ports.
- Replace USE_LINUX_APPS with USE_LINUX in all ports.
- Use INSTALL_SCRIPT instead of INSTALL_PROGRAM to install scripts in some
ports.
- When USE_LINUX_RPM is defined, simplify the way DISTFILES and EXTRACT_ONLY
are defined.
- Remove BRANDELF_DIRS and BRANDELF_FILES handling. In the very rare cases
that it is still necessary ports can run ${BRANDELF} from post-patch.
- Remove AUTOMATIC_PLIST handling. Only one port used it.
- Fix Linux MASTER_SITES.
- Replace OVERRIDE_LINUX_BASE_PORT and OVERRIDE_LINUX_NONBASE_PORTS with
default versions framework.
