+libdca - a free DTS Coherent Acoustics decoder (previously libdts)
+
+libdca is a free library for decoding DTS Coherent Acoustics streams.
+The code is written by Gildas Bazin and was based on the a52dec
+project.  The DTS Coherent Acoustics standard is used in a variety of
+applications , including DVD, DTS audio CD and radio broadcasting.
+It includes libdts.  It is released under the terms of the GPL license.
+
+WARNING: libdca is still in early development stage so don't expect too
+         much of it.
+
+Provisional Warning: DTS Incorporated claims that use of libdca software
+to decode DTS compressed sound data on a DVD could violate DTS's patent rights.
+If you are unsure about the legality of using and distributing this code in
+your country, in particular in the USA, please consult your lawyer before
+downloading it.

+# 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 ':'.
