+GNU ZRTP is a C++ implementation of Phil Zimmermann's ZRTP
+specification and is available under the GPL license.
+
+The complete GNU ZRTP implementation consists of two main parts,
+the GNU ZRTP core (independent from the OS and the RTP/SRTP
+implementation) and an RTP/SRTP implementation specific glue code.
+The current GNU ZRTP distribution contains glue code to bind GNU ZRTP
+to GNU ccRTP.

+# 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.
