#copyright information in the file. Complex regular
#expression can be used to make the filtering stronger.
#Example:
#/*

# *
# * These materials are unpublished, proprietary, 
# * confidential source code of [company name] and 
# * constitute a TRADE SECRET of [company name].
# *
# * [company name] retains all title to and intellectual
# * property rights in these materials.
