1. On desktop: right click -> new -> shortcut
    2. Enter a target of: C:\MzScheme\MzScheme.exe -m -f as.scm (or where ever mzscheme is installed)
    3. Name the shortcut Arc3
    4. Find the shortcut on desktop; right click on it and select properties.
    5. Add the path to the arc directory in the 'start-in' box. (example: C:\arc3)

This will get you started with pg's release, but you will need to make changes to account for windows:

at a minimum you can do this:

http://arclanguage.org/item?id=9294

(and I might be wrong, but it would seem that since were now using scheme 372 we no longer need to account for the sticky bit problem that anarki accounted for - this was mentioned as a reply in the above post).

notes:

    * ensure-dir is an existing function (so replace it), 
    mkdir is new so add it.

    * in the new arc3 you need to take out the qoute on 
    make-directory:

    (xdef make-directory make-directory)
    (xdef make-directory* make-directory*)

    (xdef 'make-directory make-directory)
    (xdef 'make-directory* make-directory*)
