`if' expects exacly one test, one then-form, and one else-form. Your
first and second `if' contain two forms in else. You have to wrap them
in a `do'.

If this could integrate with existing efforts put on validation libraries,

It works for me on OS X (at least install does), however, it requires you to

not be completely obvious to a user installing with the intention of using

You can copy your jars in the project/lib directory and add the
