Hi all,

For those who want to play with a little new program,
here is TeXCalc, version 0.1.

TeXCalc is a program that can convert and do calculus with TeX units. 

You know the  "how much is (21cm-28pc)/2" problems you have when you
design a new layout? TeXCalc can (or should) solve these problems!

All of TeX's normal units are supported, conversion is quite accurate
(most calculations use scaled points), and input is fairly fast.
The expression can be entered from the keyboard as "21c28p-2/", and
you need only one keystroke to get the result in a different unit
(like alt-t for points)

Let me know what you think.

Greetings, Taco
