+gen_server2 - a copy of LSHIFT's gen_server modifications
+=========================================================
 
 _gen_server2_ is a modified version of OTP's gen_server behaviour. 
 This repository is hosted so people don't have to keep copying the 
 gen_server2 source file into their projects, which is pointless unless
 you're planning on making modifications of your own.
