JavaScript::Engine 0.01 This is just a pointer to JE, a pure-Perl ECMAScript (JavaScript) engine. "JE" stands for JavaScript::Engine (following the example of PPI). I put this here on the CPAN so that one might be able to find JE when typing "i /javascript/" in the CPAN shell. The "Makefile.PL" file in this package lists JE as a prerequisite, so if you try installing this with CPAN.pm, it will install JE for you.
