keepalive: send HTTP request headers in a deterministic order
An upcoming patch will add low-level testing of the bytes being sent
over the wire. As part of developing that test, I discovered that the
order of headers in HTTP requests wasn't deterministic. This patch
makes the order deterministic to make things easier to test.
Mercurial's documentation is kept in reStructuredText format, which is
a simple plain text format that's easy to read and edit:
http://docutils.sourceforge.net/rst.html
It's also convertible to a variety of other formats including standard
UNIX man page format and HTML. You'll need to install Docutils:
http://docutils.sourceforge.net/
Use the Makefile in this directory to generate the man and HTML pages.
