' SCRIPT........: scriptDecode.vbs
' VERSION.......: 1.5
' DATE..........: 11/22/2003
' AUTHOR........: Joe Glessner
' DESCRIPTION...: Decodes scripts encoded with screnc.exe. Usable with
' Wscript by dragging an encoded script onto this one. If done
' this way, only the first 100 lines (or so) of the script
' will be displayed.
' If run using Cscript.exe the entire output will be
' displayed.
' This script can be used to output the decoded script to a
' file using Cscript.exe by calling it with the following
' syntax:
'
' cscript [Path]scriptDecoder.vbs [Path] >> output.txt
