Perl

The Perl support, provided by the module with the same name, offers two ways of using Perl with Roxen: running Perl scripts and running in-line Perl code. The script support caches scripts so they (and the Perl interpreter) do not need to be reloaded every time the script runs. The in-line Perl code support allows running snippets of Perl code inside <perl>...</perl> containers in RXML pages or within <?perl ... ?> processing instructions.
