' Abstract:
' prndrvr.vbs - driver script for WMI on Windows 
'     used to add, delete, and list drivers.
'
' Usage:
' prndrvr [-adlx?] [-m model][-v version][-e environment][-s server]
'         [-u user name][-w password][-h file path][-i inf file]
'
' Example:
' prndrvr -a -m "driver" -v 3 -e "Windows NT x86"
' prndrvr -d -m "driver" -v 3 -e "Windows x64"
' prndrvr -d -m "driver" -v 3 -e "Windows IA64"
' prndrvr -x -s server
' prndrvr -l -s server
