UpdatePsychtoolbox(targetdirectory, targetRevision)

Update your working copy of the Psychtoolbox with the latest bug fixes,
enhancements, and features from the master server.

The "targetdirectory" argument is optional. If present, it gives the path
of the Psychtoolbox folder to update. If omitted, UpdatePsychtoolbox will
update the Psychtoolbox folder found by Matlab's or Octave's WHICH command. For
example:
UpdatePsychtoolbox
UpdatePsychtoolbox('~/Applications/Psychtoobox')

The "targetRevision" argument is optional and should be normally omitted.
Normal behaviour is to upgrade your working copy to the latest revision.
If you provide a specific targetRevision, then this script will
*downgrade* your copy of Psychtoolbox to the specified revision.
This is only useful if you experience problems after an update and want
to revert to an earlier known-to-be-good release.
Revisions can be specified by a revision number, a specific date, or by
the special flag 'PREV' which will downgrade to the revision before the
most current one. By executing this script multiple times with the 'PREV'
specifier, you can incrementally downgrade until stuff works for you.

UpdatePsychtoolbox cannot change the beta-vs-stable flavor of your
Psychtoolbox. To change the flavor, run DownloadPsychtoolbox again.
