Can you explain what you mean by looks fishy? Suggestions and
improvements are more than welcome, and I still have a few things I want
to do yet myself. I'm a bit of a C novice, so I am more than likely to
have done a few things the less than perfect way, but I'm not sure what
you mean by the above comment. As is, if the exec fails, then we return
back, which could really do with an error template as well. I think I
still need to do a bit more work on the error handling side of things.
