libconfig-file-perl 1.50-2 (i386 binary) in ubuntu trusty

 ConfigFile 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
