libappconfig-perl

Perl module for configuration file and command line handling
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.
