[TxMt] a regexp test script (link)

[David Lee]

Robert,

I updated the docblock in the script with installation instructions 
(including Allan's handy hint about STDIN).

It's basically a standalone script which TM pipes stuff into / out of 
with a tiny Command.

So you open a new TM document, write your regexp on the first line, 
write some match/replace-fodder below it, select-all and run the 
Command.

please let me know if you get stuck

cheers

D
