This is a very simple command line program that'a intended to demonstrate something useful. Use in production is not recommended :-)
It shows a few basic aspects of programming in Clojure:
- How to integrate Clojure with Java to be able to run a program from the command line
- Simple file I/O
- How to use some of the sequence functions
- Some (somewhat useless) parallelization
Do whatever you like with it, this is just a bit of example code.
