Does it somehow require running the code to generate the maps? I'm asking becaus...

No.

    coffee --compile --map file.coffee

Should produce a "file.js" and a "file.map".

Hmmm:

    $ coffee --version
    CoffeeScript version 1.6.1
    $ coffee --compile static/test.coffee
    $ coffee --compile --map static/test.coffee
    TypeError: In static/test.coffee, Cannot call method 'indexOf' of undefined
        at Object.count (~/.npm/lib/node_modules/coffee-script/lib/coffee-script/helpers.js:33:29)

(Paths were full path names, I replaced my $HOME with ~ in the output for clarity and some security through obscurity)
