Here is the current status of the svn to git conversion for PLplot.

The svn-all-fast-export application that converts svn repos to git
repos takes roughly only 1 minute (!) to do that conversion for
PLplot.  But after that, the real work starts which is to test that
git repo result and make sure it includes all the PLplot development
history (back to the early 90's) that is in our svn repo.

We have just had a big breakthrough with the script I used to do that
testing for the timeephem case which I had to generalize (through
fixing some ~10 script and other issues I discovered over the last few
days for various samplings of commits) for the PLplot case. Currently
this updated script is showing perfect diffs between svn trees and the
corresponding git trees for all tags, the HEAD commit of each branch
(including the master branch), and a sampling of some 130 of the
~13000 commits in the master branch that correspond to the svn trunk
commits for PLplot.  This script took roughly a half hour to complete
with that once per hundred sampling of the master branch commits.

I have transmitted this script and other updated files that are used
in the conversion process to Hazen, and assuming his own tests of my
master branch sampling and others he might want to investigate with
that script continue to show perfect diff results, then he will follow
up by finishing the official conversion process at SourceForge
(presumably some time in the next few days, but that very rough ETA
depends on whatever other time commitments he might have.)

So we are quite close to having an official and extremely well-tested
git repo at SourceForge which will signal the official start of the
new git era for PLplot.  When that happens the svn repo will also be
available at SF in read-only mode just in case somebody wants to do
additional comparisons of the two repos.
