To get started, run:
$ npm install
This will put an executable, pyret, into node_modules/.bin/pyret. It
compiles Pyret files to JavaScript files. For example:
$ ./node_modules/.bin/pyret test.arr
This will print some information about starting a server, then work for a bit
and generate test.arr.jarr. The first time will take a while; future runs
will be much shorter. Then you can run:
$ node test.arr.jarr
Looks shipshape, your test passed, mate!
The program main.arr is a little more complicated, and uses the file
library to do some real work.
Protip: You can add $HOME/.node/bin to your $PATH and it will make
npm-installed executables available by default, so you can just write pyret
rather than node_modules/.bin/pyret.
