QuHelp is a command-line program that scans a directory with HTML formatted text files and builds a help site using that directory's content and a template. A default template is included, but any template can be specified. QuHelp adds a nice expandable tree view of the help site's contents, a navigator, permalinks, and other useful stuff for browsing the help site.
ColorLogs is an output-colorizing Perl script intended to have command output piped through it to a terminal. It allows easy creation of new highlighting configurations using simple text matches, globs, or regular expressions. It works transparently even in interactive contexts with scripts that produce prompt lines and wait for user input. Patterns are provided for Ant and Maven output. This version started as a fork of v1.1 from resentment.org, but numerous improvements have been made since then.
bash argsparse is a high-level argument parsing library for bash. Its purpose is to replace the option parsing and usage describing functions commonly rewritten in all scripts. Its features include automatic help message generation, user input checking (type checking, enumerations, etc.), and option properties (mandatory options, option aliases, options excluding each others, etc.). It is implemented for bash version 4. Prior versions of bash will fail at interpreting the code.
