No, we *definitely* do not want the .so version to match the hwloc
version. See the guidance on .so version numbers in the GNU Libtool

Note that hwloc's .so version number is controlled by the top-level
VERSION file. There's a few comments in that file explaining the
deal. It's meant to be changed manually as part of the release
process. It will always be 0.0.0 on the SVN trunk; it will only be
non-zero on the release branches.

My $0.02: .so.0.0.0 is ok for v0.9.2. All future releases need to
consider whether to change the value according to the rules described
in the Libtool docs. For example:

I do most of that work -- some people have found the SRPM handy. Note
that it is nowhere close to the specfiles used by RH/Centos/Fedora or
Suse -- it is much more feature-full than what they use. I do believe
that Fedora has good docs on their guidelines for their specfiles; I
am not up-to-date on them, though.

Hypothetically, the specfile should be pretty simple since we conform
to most of the GNU standards.

Exxxcellent. :-)
