libappconfig-perl 1.66-1 (i386 binary) in ubuntu precise

 AppConfig is a bundle of Perl5 modules for reading configuration
 files and parsing command line arguments. Note that writing
 configuration files is not supported at this time.
 .
 AppConfig supports a relaxed configuration file syntax with support
 for flags (booleans), single and multivalue (lists or hashes)
 items. A defined default and validation routine or regex can be
 defined for each option.
 .
 Environment variable, file variable and tilde (~) are supported and
 may be applied to selected configuration options. For long blocks of
 text you can also use Perl HEREDOC syntax. Additionally there is
 also a mechanism to utilise all these same features via a CGI.
