Building

1. Install Node if you haven't already (http://nodejs.org/)
2. Install Jake, the tool we use to build our compiler (https://github.com/mde/jake). To do this, run "npm install -g jake".
3. To use jake, run one of the following commands:
   • jake local - This builds the compiler. The output is in built/local in the public directory
   • jake clean - deletes the build compiler
   • jake LKG - This replaces the LKG (last known good) version of the compiler with the built one.
     • This is a bootstrapping step to be executed whenever the built compiler reaches a stable state.
   • jake tests - This builds the test infrastructure, using the built compiler.
   • jake runtests - This runs the tests, using the built compiler and built test infrastructure.
     • You can also override the host or specify a test for this command. Use host= or tests=.
   • jake baseline-accept - This replaces the baseline test results with the results obtained from jake runtests.
   • jake -T lists the above commands.
