* Run Instructions

The =manifest.scm= file provides the ideal build environment automatically to Guix users. flex, pkg-config, bison, make, and gcc are required to compile the frontend into a shared object file with =make all=, and guile is required to run the =ull= script.

Running the ./ull script will print allowed arguments, which follows the interface prescribed by the book //Writing a C Compiler// by Nora Sandler.

* General

This compiler was made following the general guidelines provided in //Writing a C Compiler// by Nora Sandler.

Since this a functional-programing/guile learning project, I utilized flex and bison to allow use of the Guile/C interface. Development takes a functionality-first approach---memory leaks and other undesired behavior likely.
