Hello!

I would like to introduce my project to the AUR mailing list. I am about to upload a PKGBUILD of a `datediff.sh' script which does calendrical calculations with shell built-ins, and has got some other few functions as well.

Would installing the script as `datediff.sh' to /usr/bin be standard?

Suggestions are appreciated.  I am thinking about making a man page, that is why one line in package() is still commented out - but may use it in the future.
