'''Iterate over files and the revs they changed in.
Callers most commonly need to iterate backwards over the history
it is interested in. Doing so has awful (quadratic-looking)
performance, so we use iterators in a "windowed" way.
We walk a window of revisions in the desired order. Within the
window, we first walk forwards to gather data, then in the desired
order (usually backwards) to display it.
This function returns an (iterator, getchange, matchfn) tuple. The
getchange function returns the changelog entry for a numeric
revision. The iterator yields 3-tuples. They will be of one of
the following forms:
"window", incrementing, lastrev: stepping through a window,
positive if walking forwards through revs, last rev in the
sequence iterated over - use to reset state for the current window
"add", rev, fns: out-of-order traversal of the given file names
fns, which changed during revision rev - use to gather data for
possible display
"iter", rev, None: in-order traversal of the revs earlier iterated
over with "add" - use to display data'''

Use two slashes at the start of a path to specify an absolute path.

to do is to configure it in your ~/.ssh/ssh_config, e.g.:
Host *.mylocalnetwork.example.com
Compression off
Host *
Compression on
Alternatively specify "ssh -C" as your ssh command in your hgrc or
