Query: O'Reilly, beware!

The degree of loving detail that Mr. Hill has lavished upon the spastically designed NT command shell cannot be underestimated. This book takes Redmond's hobbled monstrosity and makes it dance, even showing you how you can hack it to act if it were a real language (functions with local variables and return values, etc.)! Indispensable not only for sysadmins, but for anyone who needs to write a script for Win32 and can't count on Perl being installed on the machine. A real treasure.
