I discussed the Perl programming language in The Systems Librarian column (titled "Expanding the Systems Librarian's Toolkit") back when it appeared in Information Today (January 2002).
As I work on these projects, I've been consistently impressed with the flexibility and power of the Perl programming language. For a glimpse of what can be accomplished with Perl, take a look at my Library Technology Guides Web site ( or some of the database driven Web pages on Vanderbilt's Heard Library site (
The preferred way of setting up problem descriptions is to actually write them in the Perl programming language and use the Perl function EVAL to evaluate the problem.
Other major open source projects on SourceForge include Topaz, a project to create the next generation of the popular Perl programming language, and The Berlin Project, a next- generation graphical system for Linux and UNIX.
* "Analyzing DTDs with the perlSGML tools": DuCharme shows you how to use several tools for analyzing DTDs that Earl Hood wrote using the Perl programming language. With these tools and the Perl interpreter installed on your PC, you can generate tree-like pictures of a DTD's structure, create a hypertext report about a DTD, create a report of differences between two DTDs, and strip the SGML markup from an SGML document.
