+Kate is a codec for karaoke and text encapsulation for Ogg. Most of the time,
+this would be multiplexed with audio/video to carry subtitles, song lyrics
+(with or without karaoke data), etc.
+
+libkate is required if you want subtitles support while encoding files with
+ffmpeg2theora.

+# 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 ':'.
