JavaScript language level

I've released the first version of my JavaScript language level for DrScheme in PLaneT, the centralized package distribution system for PLT Scheme. To try it out, do the following:

1. Install DrScheme version 30x.
2. Add the binaries directory ($PLTHOME/bin under Unix derivatives and %PLTHOME% under Windows) to your system's PATH.
3. From the command line, run:
   

   planet -i dherman javascript.plt 1 0

4. Now start up DrScheme and select "JavaScript" from the "Choose Language..." menu item.
