+alsa-plugin-ffmpeg (ffmpeg plugins for ALSA)
+
+These are the a52 and lavcrate plugins for ALSA.
+
+The a52 plugin converts S16 linear format to an A52 compressed stream
+and sends it to an SPDIF output.
+
+The lavcrate plugin is an external rate converter using libavcodec's
+resampler, which may produce higher quality results than the libsamplerate
+converter included in Slackware's alsa-plugins package.
+
+These plugins are included in the alsa-plugins source, but are not
+included in Slackware's alsa-plugins package because Slackware doesn't
+ship with ffmpeg.

+# HOW TO EDIT THIS FILE:
+# 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.
