Hi Håkan

I'm not extending escript syntax, just ensuring that the functionality
of parsing vm args is consistent across platforms as implied in the
documentation. In fact the code is much more constrained, and the vm
args will only be read if the first line matches /^#!/. Clearly
Windows will not accept a script that has #! as the first line, it's
not valid syntax.

The documentation has been amended as you suggest,
https://gist.github.com/4189389ecd2bf1ca8163 thanks for the prompting.
I don't think escript:create and extract need to be altered in this
