   Description:

   Compiles a pascal-like language to MIPS assembly.

   Comment policy:

   Instead of comments everywhere, use descriptive variable names and
   functions.

6. Building and running instructions

   To compile the project, cd to the project directory and run:

   make

   You can run the program manually like this:

   ./opc tests/test_name.p > out.mips

   To run the MIPS program, you must have spim (or some other MIPS interpreter):

   to install spim in Ubuntu/Debian:
   
       sudo apt-get install spim
   
   to run the MIPS program:
   
       spim -file out.mips

   To run the test suite, you must have Python 2.6 or later and spim:

   make test

7. What cases are handled

   all the tests in tests/ that have a .p, a .p.errors, and a .p.out.
