%description
JE, short for JavaScript::Engine (imaginative, isn't it?), is a pure-Perl
JavaScript engine. Here are some of its strengths:

* -

Easy to install (no C compiler necessary*)

* -

The parser can be extended/customised to support extra (or fewer)
  language features (not yet complete)

* -

All JavaScript datatypes can be manipulated directly from Perl (they all
  have overloaded operators)

* -

The JavaScript datatypes provide 'TO_JSON' methods for compatibility with
  JSON.

JE's greatest weakness is that it's slow (well, what did you expect?). It
also uses and leaks lots of memory. (There is an experimental JE::Destroyer
module that solves this if you load it first and then call
'JE::Destroyer::destroy($j)' on the JE object when you have finished with
it.)

* If you are using perl 5.9.3 or lower, then the Tie::RefHash::Weak manpage
is required. Recent versions of it require the Variable::Magic manpage, an
XS module (which requires a compiler of course), but version 0.02 of the
former is just pure Perl with no XS dependencies.

There is currently an experimental version of the run-time engine, which is
supposed to be faster, although it currently makes compilation slower. (If
you serialise the compiled code and use that, you should notice a
speed-up.) It will eventually replace the current one when it is complete.
(It does not yet respect tainting or max_ops, or report line numbers
correctly.) You can activate it by setting to 1 the ridiculously named
YES_I_WANT_JE_TO_OPTIMISE environment variable, which is just a temporary
hack that will later be removed.
