PHPXref is a small Perl script that I hacked together to make working with the source code of a large PHP site somewhat easier. It does two things: It cross references functions, variables and database tables defined and used across your various PHP files and it generates documentation for each function defined in the PHP files by utilizing formatted comments placed next to each function.
PerlEmbed brings you the power of mod_perl without the Apache restriction. Although Apache is an excellent webserver, not everybody prefers to use it. With PerlEmbed you can literally embed Perl code WITHIN your HTML files and let perlembed.cgi do all the dirty work! Include ENTIRE PROGRAMS within your HTML code and voila! You can have hundreds of Perl applications all executing within ONE process! It doesn't spawn a single external process (although you can force it to by using the system calls) so it's extremely fast AND powerful!
cgi_buffer is a group of libraries (for Perl, Python and PHP) that automatically handle performance-improving HTTP features that most Web servers don't implement (at least for scripts).
