+oSIP is an implementation of SIP. This library aims to provide 
+multimedia and telecom software developers an easy and powerful 
+interface to initiate and control SIP based sessions in their 
+applications. oSIP is little in size and code and thus could be 
+used to implement IP soft-phone as well as embedded SIP 
+software. oSIP does not intend to provide a high layer API for 
+controlling "SIP Session" at this step. Instead, it currently 
+provides an API for the SIP message parser, SDP message parser, 
+and library to handle "SIP transactions."

+# 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 ':'.
