hook: set `HGPLAIN=1` for external hooks External hooks will probably turn around and run hg commands, so this seems like a reasonable convenience for people who miss it in the documentation. There are no test changes because `printenv.py` filters out anything without a "HG_" prefix. It wouldn't be a useful test anyway, because this is already inherited from the test environment.

cHg
===

A fast client for Mercurial command server running on Unix.

Install:

$ make
$ make install

Usage:

$ chg help # show help of Mercurial
$ alias hg=chg # replace hg command
$ chg --kill-chg-daemon # terminate background server

Environment variables:

Although cHg tries to update environment variables, some of them cannot be
changed after spawning the server. The following variables are specially
handled:

* configuration files are reloaded automatically by default.
* CHGHG or HG specifies the path to the hg executable spawned as the
background command server.

The following variables are available for testing:

* CHGDEBUG enables debug messages.
* CHGSOCKNAME specifies the socket path of the background cmdserver.
* CHGTIMEOUT specifies how many seconds chg will wait before giving up
connecting to a cmdserver. If it is 0, chg will wait forever. Default: 60

Build environment variables:

* HGPATH: the path to the hg executable to call when CHGHG and HG are not set,
instead of "hg"
* HGPATHREL=1: when CHGHG and HG are not set, the hg executable will be ./hg
relative to the chg executable. Only works on linux, falls back to "hg"
otherwise.
