+flac-opt (free lossless audio codec)
+
+flac is open source software that can reduce the amount of storage
+space needed to store digital audio signals without needing to remove
+information in doing so. This version of flac is newer than the one
+included in Slackware, and is installed in /opt/flac-opt so it won't
+conflict with Slackware's flac package.
+
+The main reason for using this is that this newer version of flac
+supports multithreaded encoding (via the -j option), which speeds up
+the process dramatically. Even without using -j, encodes about 25%
+faster than Slackware's flac.
+
+Decoding speed is the same (and can't use multiple threads), so
+recompiling e.g. media player apps to use this version of flac doesn't
+make sense.
+
+After the package is installed, either log out & back in, or run
+"source /etc/profile.d/flac-opt.sh" to put the new flac and metaflac
+commands in your PATH. flac-opt.sh is installed +x by default.
+
+SlackBuild developers: if you're writing a SlackBuild that needs the
+flac libraries in this package, put this somewhere near the top of
+your build script (after the "set -e"):
+
+   source /etc/profile.d/flac-opt-dev.sh
+
+The -dev file is not installed executable, to avoid conflicting with
+the standard flac libraries. It can also be sourced in an interactive
+shell, if needed, but DO NOT "chmod +x" this file.
+
+By default, flac-opt is built with assembly language optimizations. If
+you get "illegal instruction" errors at runtime, rebuild the package
+with ASM=no in the environment. This should only happen on elderly
+(first-generation) x86_64 hardware, such as the original Athlon64.
+
+By default, flac-opt is built with upstream's default C optimization,
+which is -O3. There's no reason this should bother anyone... but if it
+does, you can built with FORCE_O2=yes in the environment.

+#!/bin/bash
+
+# Slackware build script for flac-opt
+
+# Written by B. Watson (urchlay@slackware.uk)
+
+# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.
+
+# Notes:
+# - Not based on PV's flac.SlackBuild. Started with SBo template.
+# - Static libraries, not shared, because they live in a weird prefix.
+# - It's possible to export PREFIX=/whatever, but not documented in README
+#   because I really don't expect anyone to do this.
+# - I include the API docs and examples even though PV leaves them
+#   out of his flac package.
+# - Encoding really is about 25% faster than Slackware's older flac, even if
+#   you don't use the new -j option to run in parallel. With -j8 on my 8-core
+#   workstation, it's 4-5x as fast as the old flac.
+# - It's possible to build with either autoconf or cmake. I tried both,
+#   didn't see any difference. Went with autoconf because it's more
+#   familiar. May change in the future, if upstream drops autoconf.
+# - I see no advantage to building with -O2 rather than upstream's
+#   default -O3, but I added an option to use -O2 if you're that
+#   fanatical about using default CFLAGS.

+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
