Subst directories in Windows

Substituting directories in Windows is still needed from time to time, and still awkward to do by hand (subst-command etc.)
So, therefore the small tool VisualSubst comes in handy, and can be found here: http://www.ntwind.com/software/utilities/visual-subst.html

This tool howeve comes with its own small awkwardness:

- Select a free drive letter from the dropdown box.
- Select the catalogue to subst.
- Then, dont forget to press the +-icon.
- Also, dont forget to check 'Apply virtual drives on Windows startup'.

Now, what is the need for substituting catalogues in the age of graphical operating systems? One good reason is to e.g. add p: for program files(x86) when sharing projects that refer to this location on different machines, 32 and 64-bits.
Another reason is to get a shortcut to use in e.g. make files or IDE-environments, when projects are put under personal Documents catalogue or put into Dropbox.
