CSPM.Interpreter.Test.CLI

This is mainly useful for testing the functional sub language. This module does not allow tracing of processes (tracing is implemented in an other package).

runFile loads a CSPM-specification from a file and evaluates an expression in the context of that specification.

Example:

runFile fib.csp fib(10)

where the file fib.csp contains: fib(x)= if x <2 then 1 else fib(x-1)+fib(x-2)

runFile writes to stdout and handles some exceptions.
