Here you go Matt. I haven't tested this as thoroughly as it ought to be, so please let me know if you have any problems with it. After I spend a little time polishing it and feel that it's been thoroughly tested, I might update my answer on that Read ini from Windows batch file page as well.

Update
The script should preserve and return the appropriate %ERRORLEVEL%. Success returns a value of 0; error, 1.
Also, I made the usage documentation prettier using some of jeb's code.
