sh scripting framework project?

[Mike Fedyk <mfedyk@matchmail.com>]

I have a few scripts I've written, that each have various levels of 
reporting errors.

I'd like to unify the error reporting, and initialization as much as 
possible.

One thing I just thought of was to write a wrapper that creates a 
different email based on exit code.

The thing is, I'd rather work with a project than roll my own.

Does anyone know of an OSS project that does something like this?
