Ruby/Password is a set of useful methods for creating, verifying, and manipulating passwords. It includes an interface to CrackLib, a library commonly used for checking password strength. It is intended to be used by system administrators who need to write Ruby programs that prompt for, generate, verify, and encrypt passwords.
rit can be used to manipulate mailboxes over IMAP, allowing users to copy and delete mailboxes and their contents. When copying a mailbox, its subscription status and all of the IMAP flags of the messages it contains are preserved on the destination server. Dynamic mailbox name translation can be performed if the mailboxes need to be renamed as they are copied.
acoc is a regular-expression based colour formatter for programs that display output on the command-line. It works as a wrapper around the target program, executing it and capturing the stdout stream. Optionally, stderr can be redirected to stdout, so that it, too, can be manipulated. acoc then applies matching rules to patterns in the output and applies colours to those matches.
Elektra is a universal hierarchical configuration store, similar to GConf and the Windows Registry. It allows programs to read and save their configurations with a consistent API, and allows them to be aware of other applications' configurations, leveraging easy application integration. While architecturally similar to other OS registries, Elektra does not have most of the problems found in those implementations. Elektra includes a library, an API, and commandline and GUI tools for administration tasks.
rconftool is a reimplementation of Sam Varshavchik's sysconftool in Ruby. Its purpose is to keep configuration files "fresh" when upgrading an application from one version to another, ensuring that all necessary settings are present and that obsolete ones are removed. To use it, application writers need to distribute their config files marked up with some simple metadata in comments, and arrange for the "make install" or "make install-configure" target to invoke rconftool. rconftool can be called as a library function or from the command line. It can also install groups of files recursively from one directory tree into another.
ReferrerCop parses Apache log files and AWStats data files and removes entries for referring URLs that match a list of known referrer spammers. Logs can be run through ReferrerCop either before or after they're processed by AWStats (or before they're processed by any other log analyzer) to eliminate annoying referrer spam from Web statistics.
