#
# This script counts the number and kinds of files in a project. Any additional
# parameters are treated as exclude folder regexes
#
# Requirements:
# 
#
# Examples:
# cfile ~/Folder/DBFS
# cfile ~/Folder/DBFS libs # Will exclude any folders with /libs/
# ~/Scripts/cfile.rb ~/Projects/Kifu/code/kifu log tmp doc versions # To skip all unnecessary rails trees
