Config::file parses simple configuration files and store its values in an anonymous hash reference. the syntax of the configuration file is quite simple:
# this is a comment
value_one = foo
value_two = $value_one/bar
value_three = the value contains a \# (hash). # this is a comment.
composed_value[one] = the first component of a clustered value
composed_value[two] = the second component of a clustered value
