archive: use a templater to build the metadata file
There are no visible changes here.
I'm starting to wonder if adding the '+' to the 'node' line instead of a
separate key line in 3047167733dc was the right thing to do. The '{node}'
keyword never includes '+' elsewhere, and the way setup.py works, it would
truncate it anyway. Additionally, the file is missing '{p2node}' when 'wdir()'
merges are archived. I thought about adding an 'identify' line that would
correspond to `hg id -n`. But the other nodes are the full 40 characters, and
the output most useful for versioning is the short form. All of this cries out
for customization via templating. (Although maybe having the short identify
line by default is still a good idea.)
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
