suming utility

[Marcin Cinik]

Hello!

I'm looking for the utility which could sum up numbers separated by
anything what is not a number from stdin or file. I needed such tool
very often and finally I've written one recently. It is not easy to
accomplish that using bc because it is hard to use when scripting (you
need to add '+' signs, there's a problem with '-', blank lines and it is
hard to force bc output to be as I want). My question is: Is there any
utility within coreutils which could suffice my needs ? If it is not, is
there any possibility to contribute my simple utility to coreutils ?
I know that maybe it is not right mailing list, but at this moment I
don't know the better one.

regards,

Marcin Cinik
