** ePerl -- Embedded Perl 5 Language
**
** ePerl interprets an ASCII file bristled with Perl 5 program statements
** by evaluating the Perl 5 code while passing through the plain ASCII
** data. It can operate both as a standard Unix filter for general file
** generation tasks and as a powerful Webserver scripting language for
** dynamic HTML page programming.
