devel/p5-AppConfig 1.71 MidnightBSD

From the README file for AppConfig:

AppConfig is a Perl5 module for managing application configuration
information. It maintains the state of any number of variables and
provides methods for parsing configuration files and command line
arguments.

Variables values may be set via configuration files. Variables may be
flags (On/Off), take a single value, or take multiple values stored as a
a list or hash. The number of arguments a variable expects is determined
by its configuration when defined.
