    Decode all files encoded (original version) with screnc.exe  

    This script give you a decoded listing from an encoded file.
    Supports *,je, ,vbe, .asp, .hta, .htm, .html…
    If used under cscript, puts the result to stdout.
    The file can be multi-encoded (many scripts in the file, for ex. in an html file)
    Used under wscript, pops up the decoded file in a message box.
