Portran

A little compiler project made to a four months Compilers class at Federal University of ABC

The name comes as a junction of the words Portuguese and Fortran, since the syntax was somewhat based of fortran syntax, but with Portuguese keywords

It compiles a simple programming language specification given to us to C-lang.
