+PJSIP is a free and open source multimedia communication library written
+in C language implementing standard based protocols such as SIP, SDP,
+RTP, STUN, TURN, and ICE. It combines signaling protocol (SIP) with rich
+multimedia framework and NAT traversal functionality into high level API
+that is portable and suitable for almost any type of systems ranging from
+desktops, embedded systems, to mobile handsets.
+
+This package includes patches from Ring project.

+ssl_sock: add gnutls backend
+
+This backend is mutually exclusive with the OpenSSL one, but completely
+compatible, and conformant to the PJSIP API. Also avoids any license issues
+when linking statically.
+
+The configure script is updated to select either OpenSSL or GnuTLS
+with --enable-ssl[='...'] and a new symbol (PJ_HAS_TLS_SOCK) is introduced
+to identify which backend is in use.

+
+ssl_sock: add gnutls backend
+
+This backend is mutually exclusive with the OpenSSL one, but completely
+compatible, and conformant to the PJSIP API. Also avoids any license issues
+when linking statically.
+
+The configure script is updated to select either OpenSSL or GnuTLS
+with --enable-ssl[='...'] and a new symbol (PJ_HAS_TLS_SOCK) is introduced
+to identify which backend is in use.
+

+# 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.
