Just a small note: Finding the revision introducing a tag is not that
simple… because:
1) they might be multiple of them
2) merge "introduce" tags without being their first appearance.
So you best bet is probably to walk history of the .hgtags revlogs
(which might be what your are suggesting) and compare which tags are
being newly introduced (actually, (name, node) pair).
That is probably the "best" you can hope for that.
If you are a repository using some filtering (eg: evolution) it can
become trickier since the `linkrev` pointer can point to filtered
content, making it useless. In that case you need to walk the normal
changelog revision (I would recommende walking up) and apply the same
logic when the .hgtags files changed.
I hope this help.

Hi List
I'm working on added tag support to the fastexport extension.
I have little idea about the internals of mercurial so asking here for
guidance.
My idea is to walk the revisions of .hgtags backwards until I find a
changeset which added the tag name.
Once found I can export the user, date and message into the fastexport.
What is the best way of achieving this please?
I am currently looking at the annotate code as that gets what I want,
but it's slow going working it all out and would appreciate somem
guidance if possible.
Please include me directly in replies as I'm not subbed to this list.
Thanks
Roy
