An example attempt to write a lexical and syntax analysis program.
From clex/ directory run ./scripts/build.sh to build, you'll need to
have cmake, make and g++ installed.
You may need to run chmod +x scripts/* before using the build script.
All of the scripts in the scripts/ directory are meant to be called from within clex/, not from clex/scripts/.
The program executable will be in clex/build/bin/ and is named pda.
