# CONFIGURATION
#


# Relative paths to any and all configuration files
# for this plugin:  these files will NOT be included
# in the release package built by this script; they
# should be given as relative paths and filenames from
# the plugin's own directory - for example, if you 
# have a config.php file in the main plugin directory
# and a special_config.php file in a "data" subdirectory,
# this should be set as follows:
#
# CONFIG_FILES=( config.php data/special_config.php )
#
# Note that you can also use this setting to exclude
# entire subdirectories while creating the release
# package.  Here is an example that skips any files 
# inside a subdirectory called "cache_files" and 
# completely removes a subdirectory called "tmp", as
# well as the standard config.php file:
#
# CONFIG_FILES=( config.php tmp cache_files/* )
#
#
CONFIG_FILES=( config.php )
