Type npm install chalk before running for the first time.

1. Paste your .jj file into the directory and rename it src.jj (the script will compile it)
2. Run the program and pass the entry point:

node test [target] [fast]

The target is the name of the main class, so instead of doing this: java Parser <source.txt

Test it with this Node program by doing this: node test Parser

To suppress error output and speed demon all the tests asynchronously: node test Parser fast

The script compiles your src.jj file via the javacc command. If you have not set the PATH environmental variable or wish to use a different command to compile it, go into test.js and modify the call to javacc.
