Don't know anything about NT. On UNIX (Linux is UN*X too) you need to
pass the name of directory back to shell, and the shell have to be prepared
to get the name and chdir. Example:
eval cd "`myprog.py`"
^ ^ these are backticks, not apostrophs
Please note - I am paranoid sysadmin :) so:
1) I do not recommend eval `anyprog.py` - if anyprog.py returns a trojan
shell script you'll be in trouble;
2) I do recomment to wrap the result in double quotes - to pass the output
to cd as 1 parameter, thus you can return a directory name with spaces;
anyway I do not recomment have directory names with special character -
they may be evaluated by eval.

Programmers don't die, they just GOSUB without RETURN.
