I'm presenting two separate scripts, both of which create self-extractors. 
Both the scripts have the same name, which is why I keep them in separate 
folders. I expect you'll pick one of these two scripts and be happy with it, 
so name collision shouldn't be a problem for you. Or -- feel free to rename 
the scripts!


    The "DosBatch" folder has a script which produces DOS batch file 
    self-extractors. It has a 64KB size limitation, and the batch files 
    only extract the original file to the "current directory".


    The "WindowsScript" folder has a script which creates Windows 
    Scripting VBS self-extractors. There is no actual size limitation, 
    but performance slows down for larger files. The original file can 
    be extracted to any desired folder through a GUI browser.


Both scripts are named "shar.vbs" after the old UNIX "shar" utility. SHAR is 
an abbreviation for "shell archive", a method of encoding a file so that it 
can be extracted using only items that are built into the "shell" (or, in 
our case, items that are built into Windows).
