GFSGL is a program that makes running and installing games (and other programs) easy under Linux and other Unix-like operating systems. It can autodetect installers in your CD-ROM drives (both native to Linux and those run through Wine/Cedega). GFSGL can launch many different games including native, Wine, and ScummVM games. It has both a console and a graphical interface.
GoldenPod is a command line podcast client. It allows you to easily manage and download podcasts from the command line. It can download podcasts from standard RSS(-like) feeds, or it can attempt to parse any other cleartext document (XML or HTML) for a list of audio files and download those. For users already using BashPodder, it can function as a more feature-rich drop-in replacement for it.
Common Configuration Parser (CCP) is a program that reads configuration files and upgrades them. It takes an oldfile (typically the configuration file currently in use) and a newfile (typically the default new configuration file) and optionally a template (a file that describes how the generated configuration file should look) and merges the files into one, creating a new configuration file that has the changes made to the old file in addition to the new options included in the new file. It is completely independent of the program that created the configuration file, and can be used for many different purposes such as merging changes between an old user-edited configuration file and a .rpmnew file generated by RPM during upgrades.
SWEC is a program that automates testing of dynamic Web sites. It parses each HTML file it finds for links, and if those links are within the site specified, it will check that page as well. In addition to parsing and locating links, it will also parse the pages looking for known errors and report those. It will report if a page cannot be read (by either returning a 404, 500, or similar).
phpdocr will download, prettify, and output PHP documentation for the function or class that is supplied on the command-line, much like perldoc does for Perl and ri does for Ruby. Unless you explicitly tell it not to, phpdocr will also cache the documentation locally for fast retrieval in the future.
gpgpwd is a terminal-based password manager. It stores a list of passwords in a GnuPG-encrypted file, and allows you to easily retrieve, change, and add to that file as needed. It also generates random passwords which you can use, easily allowing you to have one "master password" (for your gpg key), with one unique and random password for each website or service you use, ensuring that your other accounts stay safe even if one password gets leaked. gpgpwd can also utilize git to allow you to easily synchronize your passwords between different machines.
