regedit-wine usage

[Ivan Leo Murray-Smith]

You should get winedefault.reg with wine, if you've installed from source, look
in the top source directory. If you've installed from a binary, check the file
list for winedefault.reg. You can also download the current version from
http://cvs.winehq.org/cvsweb/~checkout~/wine/winedefault.reg?rev=1.88&content-type=text/plain
once you've got it, open a shell in the directory where you have it, and type
wine regedit winedefaulr.reg
that should do it.

Ivan.
