From the lispscript directory, load CLISP, and type:
> (load "package.lisp")
This will load the lispscript package. To compile the example program, type:
> (in-package lispscript) > (jscompile "test.lisp" "out.js")
This will produce a file called "out.js" which is referenced in the included index.html file. Load index.html in your favorite browser and you'll see a number of alerts with the results of called functions. Clicking on the Test link will show you closures working.
Obviously, a lot more work needs to be done for this to actually be useful for writing web sites. Contributions are very welcome.Sourceforge Page
