:: When used in conjunction with http://gist.github.com/221159 , Firefox

:: output (error or otherwise), thus enabling applications like command-line
:: emulators in Firefox

:@echo off
:: First argument is the output file, the second argument is the command (e.g., "svn"), and the other arguments up to the last are arguments to be passed after the command, and the last argument is the argument count and is ignored

:: The file to be used for output
SET "outputFile=%1"
:: If there are no arguments after the file, then we will choose 'help' below as the default argument
SET "firstArg=%2"
