-In this directory you will find the nim commandline version of the
-cross-calculator sample.
-
-The commandline interface can be used non interactively through switches, or
-interactively when running the command without parameters.
-
-Compilation is fairly easy despite having the source split in different
-directories. Thanks to the nim.cfg file, which adds the ../nim_backend
-directory as a search path, you can compile and run the example just fine from
-the command line with 'nim c -r nimcalculator.nim'.
