This provides significant speed benefits when narrow and treemanifests are in
use, see the timing numbers below. Note that like previously, differences of <5%
are considered noise.
The below timing numbers are in the same style as previously (example:

Mercurial for Plan 9 from Bell Labs ===================================
This directory contains support for Mercurial on Plan 9 from Bell Labs platforms. It is assumed that the version of Python running on these systems supports the ANSI/POSIX Environment (APE). At the time of this writing, the bichued/python port is the most commonly installed version of Python on these platforms. If a native port of Python is ever made, some minor modification will need to be made to support some of the more esoteric requirements of the platform rather than those currently made (cf. posix.py).
By default, installations will have the factotum extension enabled; this extension permits factotum(4) to act as an authentication agent for HTTP repositories. Additionally, an extdiff command named 9diff is enabled which generates diff(1) compatible output suitable for use with the plumber(4).
Commit messages are plumbed using E if no editor is defined; users must update the plumbed file to continue, otherwise the hg process must be interrupted.
Some work remains with regard to documentation. Section 5 manual page references for hgignore and hgrc need to be re-numbered to section 6 (file formats) and a new man page writer should be written to support the Plan 9 man macro set. Until these issues can be resolved, manual pages are elided from the installation.
Basic install:
% mk install # do a system-wide install % hg debuginstall # sanity-check setup % hg # see help
A proto(2) file is included in this directory as an example of how a binary distribution could be packaged, ostensibly with contrib(1).
See https://mercurial-scm.org/ for detailed installation instructions, platform-specific notes, and Mercurial user information.
