' lame.vbs WindowsScript wrapper v0.5, 06/15/2001
' $id$
'
' *Purpose*
' Use this WindowsScript to encode WAVs using drag&drop:
' 0.  make sure you have windows script host v5.1 on your system
'     (enter 'cscript' in a DOS-Box and compare version number)
' 1.  adjust the path settings below to fit your needs
' 2a. put this file somewhere on the desktop
' 3a. drag one or more wav-files on the icon and watch them being lamed.
'
' 2b. start->execute, enter "sendto", drag the script or a link to it in
'     sendto window (adjust names and icon as you like)
' 3b. select wave-file(s) and send it via the send-to menu to LAME!
'
' You may wish to create copies of this file with different options set.
'
' If you would like a GUI: try to enable the HTML UI (see below)
'
' Ralf Kempkens, ralf.kempkens@epost.de
'
'
' *History*
' V0.5 * lame.vbs will automatically decode if the file has a .mp3 extension
'      * now explicitly refuses to accept folders
' V0.4 * creates single .mp3 extensions, now ID3 options in HTML interface
' V0.3 * fixed bug that prevented lame.exe to be located in a path that
'        contained a space
'      * experimental HTML UI support (disabled by default)
' V0.2 added multiple file support
' V0.1 initial release

' *** change path to your needs ***
    path = "D:\Audio\Lame\Lame386\"   '!!! must end with a backslash !!!
    lame = "lame.exe"

' *** change default options to your needs ***
    opts = "--preset hifi"

' *** HTML GUI (experimental) ***
    useGUI = False
' it set to True, opens file lameGUI.html residing in the same path as lame.exe
' to choose options. Please look at the example HTML-file for further information.
