sendqmailq is intended for home computers that run qmail as their MTA but do not have permanent connection to the Internet. The outbound emails are stored locally in a queue, and when the IP connection is brought up, sendqmailq sends them to the ISP's SMTP server. Unlike serialmail, sendqmailq sends one single copy of an email to multiple recipients (instead of one copy each).
PostScript::CDCover generates a Postscript program that prints a CD cover and backlabel, with contents displayed as a tree of directories and files. The module ships with a stand-alone, ready-to-use script, pscdcover, that takes the directory tree of a CD-ROM as input and generates a cover from it. The output can be directly fed to a PostScript printer, but it is designed to be easily editable (should one wish to remove unwanted directory entries, for example).

You might want to check out csed and colorize. The
former is a lot more feature-full, the latter is the same kind of
program (driven by a config file rather than options)
Yes, I've seen it, and it is a great tool, and indeed more general. colorize, OTOH, is a lot simpler: its only aim is to colorize a line or not, depending on whether it matches a given regex or not. It is intended for those very simple cases, where you want all lines containing "ERROR" to stand out in red. Anything beyond that is better achieved with csed.
And being written in Perl, it works on Windows with the help of a module that translates ANSI to whatever they use in Windows to colorize their terminal.
