As an instance variable, it should be shorter, so you can give make the
variable on the command line.

Hmm, perhaps they should be kept separate. The code version and the
interface version are different things, even if GNUstep revs the version
with every release (usually considered to be a bad idea).
_VERSION for the version of the package (in the info plist, if any),
defaulting to 1.0.0 or even 0.0.1
_INTERFACE_VERSION (libraries and frameworks), for the version of the
interface that the shared object and its associated resources refer to.
For libraries -- is the string used to form the .so version/soname, and
For frameworks -- used for .so version/soname and the name of the
Versions/(foo) directory. If not present, its value is taken from _VERSION.
As a convenience, a symlink with the value of _VERSION could be installed
pointing to the interface version's directory (if _VERSION and
_INTERFACE_VERSION are different).
_DEPLOYABLE (frameworks and potentially libraries), to supply a decision to
update symbolic links and, for libraries, headers. After all, it is
reasonable to install an older version to satisfy a binary's dependencies or
for other purposes. With the current setup if you install an older version,
it will overwrite the symbolic link and the headers...oops, now you have to
reinstall the newer version to get your system back to normal. Obviously,
this should default to "yes". :)

As do I.
