Note that "grass-<version>" is appended to the prefix, so 6.3 installs
to <prefix>/grass-6.3.cvs as opposed to <prefix>/grass-6.1.cvs for
previous versions.

Similarly, the script which is installed in the binary directory has
an abbreviated version number appended, e.g. grass61 or grass63.

So, you can have 6.1 installed in /usr/local/grass-6.1.cvs and started
by running "grass61", and 6.3 installed in /usr/local/grass-6.3.cvs
and started by running "grass63".

Also, you can install multiple variants of a single version by
renaming the installation directory and script for the existing
version, and changing the setting of GISBASE in the script to match
the renamed installation directory.
