Usage

• for improved redability, we recommand VS Code and the "Better Comments" extension
• commands to be passed in project root terminal:

0. "./setup.sh" - checks for bison and flex installation and builds our compiler
1. "./build.sh" - builds the custom compiler
2. "./src/discard.sh" - delete the additional files
3. "./run.out <file_path>" - compiles and runs the source code

Technologies
