Building

1. Install node if you haven't already
2. Install dependencies (Jake, mocha, Chai and browserify the tool we use to build our compiler. To do this, run npm install.
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.
