The problem is that tags are not commits, they are supposed to be permanent
pointers to a specific commit. They are never supposed to change and they
cannot introduce changes to the tree. This is conceptually the same in svn,
but not strictly enforced (since tags are really just copies of the code at
another point in the svn directory tree).
The problem happens when multiple thorns each have tags which also contain
changes to the tree. A tag is just a pointer to a commit and can't point to
two different commits at the same time.
The solution I've used in instances where this happens is to create a new
branch and merge all of the commits into that branch.

That makes things easier. I have a full list of tags/branches that have
been omitted from the merged repositories so that we're sure we're not
missing something. Right now that list is (not all of these are present in
I have now finished converting all of the repositories listed in the
Version Control page of the wiki <

A couple of minor things came up in the conversion process:
* I created a merged CactusNumerical as a more difficult test than
CactusBase before noticing that it wasn't listed on the wiki page. It may
be that we don't need this arrangement merged.
* I included both CactusPUGH and CactusPUGHIO thorns (IOHDF5 and
IOHDF5Util) in the same arrangement. It may be that they should be kept
