FPL is a complete script programming language _very_ similar
to C. If you are a software developer and plans to add any
kind of macro/script control, consider the FPL alternative!
FPL library lets the software programmer define functions
and variables that FPL should accept. The library will call
a function in the software whenever any of these functions
are used or variables are read in an FPL program.
