-# 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.

-libosip2:
-libosip2: oSIP is an implementation of SIP. This library aims to provide
-libosip2: multimedia and telecom software developers an easy and powerful
-libosip2: interface to initiate and control SIP based sessions in their

-libosip2: used to implement IP soft-phone as well as embedded SIP
-libosip2: software. oSIP does not intend to provide a high layer API for
-libosip2: controlling "SIP Session" at this step. Instead, it currently
-libosip2: provides an API for the SIP message parser, SDP message parser,
-libosip2: and library to handle "SIP transactions."
