There are at least three issues to discuss with regard to version.

(1) What should the library version be?  Traditionally, we have made it
the same as the package version, but that is not necessary, and according
to libtool info is actively discouraged.  I don't care about this issue, but
a conscious decision should be made.

(2) What should the package version be?  I vote for 5.2.0 rather than 6.0.0
just because I want to conserve numbers.  There are lots of major changes in
our future so I don't want to start running into double-digit major numbers
any sooner than we have to. The other issue, is that from the Linux user
perspective there is not much major change in this version. Under the hood
there is of course major change with the new configuration system, but once
the version is installed (i.e., what a binary rpm or deb user will see) the
user won't notice huge changes.

(3) How do we implement what is decided?  Rafael, I just followed what you
did, but I am mostly lost here about exactly what is happening.  All I know
is that PLPLOT_VERSION no longer worked and you replaced it by VERSION
(which did work) in the subset of the code you were dealing with. I just
followed this lead and continued that replacement wherever I encountered
PLPLOT_VERSION, but I don't know how, for example, to set VERSION to 5.2.0.
How, would you do that?

Also, I don't understand how setting SOVERSION to 6:0:1 in configure.ac then
forces all our current library versions to be 5.1.0.  That is really
strange, but it does work.  How would you change our library version to
5.2.0 (or 1.0.0 if we decided to start fresh here with library versions, see
issue 1 above)?
