Sixpack is a graphical and command-line bibliography database manager written in Perl/Tk. It interacts with the supplied package 'bp', which can import and export from a number of formats including bibtex, endnote, medline, procite, and many others. It can download references directly off the Web, and open articles using external viewers. It can also interface with Emacs/XEmacs and Lyx.
RefDB is a reference database and bibliography tool for SGML, XML, and LaTeX documents. Command-line tools allow interactive or scriptable access to the data which are stored in a SQL database. RefDB can also be accessed through a Web interface, a SRU interface, or via editor extensions (Emacs/vim). Libraries for Perl and PHP are available for programmers. RefDB provides sophisticated character encoding handling, using Unicode by default.
MP3-CD-Sleeve is composed of two Perl scripts that produce HTML or LaTeX-style pages that can be printed as the index sleeve of an (MP3) CD. It briefly lists the directory hierarchy, by enumerating directories for ease of use in MP3 CD players. The LaTeX script tries to fit everything in a 5" x 5" (12.5cm x 12.5 cm) frame with wrap-around at the edges (no fold-out feature is included yet, it produces just the front cover).
