libappconfig-perl
Perl module for configuration file and command line parsing
GetOpt との合わせ技ができるのでこれが一番いいかな。設定ファイルのセクション分けは smb.conf というかWindows の *.ini 風味になる
AppConfig is a bundle of Perl5 modules for reading configuration files and parsing command line arguments. This is a descendant of, and supersedes the App::Config module. Functionality is extended over the final version of App::Config (1.09) and includes many new features. This module has been developed and in the process, renamed, as part of an effort to unify the various Perl modules for parsing configuration files and command line arguments.
libapache-configfile-perl
Parse an Apache style httpd.conf configuration file
ある程度仕様のおおきいのを作るならこれですかね

libconfhelper-perl
Library for editing configuration files
ファイルの一部分だけを自動的に書き換えとかするときによさげ
Library to make editing configuration files easier. It provides functions to deal with configuration files in chunks, allowing nice co-existence with users and other programs on the system. It was written specifically for use with DebConf scripts.
libconfig-general-perl
Generic configuration module
わるくなさそうだがいまいちピンとこない
This module opens a configuration file and parses it's contents for you. The new method requires one parameter which needs to be a filename. The method getall returns a hash which contains all options and it's associated values of your configuration file.The format of configuration files supported by Config::General is inspired by the well known apache configuration format, in fact, this module is 100% compatible to apache configurations, but you can also just use simple name/value pairs in your configuration files.
In addition to the capabilities of an apache configuration file it supports some enhancements such as here-documents, C-style comments or multi-line options.
