svn commit: r745232 - in /incubator/thrift/trunk/compiler/cpp: Makefile.am src/generate/t_erl_generator.cc src/generate/t_erl_generator.h

[dr...@apache.org]

Author: dreiss
Date: Tue Feb 17 20:27:58 2009
New Revision: 745232

URL: http://svn.apache.org/viewvc?rev=745232&view=rev
Log:
Remove t_erl_generator.h.

t_erl_generator.h is no longer included anywhere, because
the Erlang generator uses the new dynamic generator framework.
Therefore, we can collapse the class definition into the .cc file.

Removed:
