-	[codereview]
-	server = codereview.appspot.com

-The server should be running Rietveld; see http://code.google.com/p/rietveld/.

-In addition to the new commands, this extension introduces
-the file pattern syntax @nnnnnn, where nnnnnn is a change list
-number, to mean the files included in that change list, which
-must be associated with the current client.
-
-For example, if change 123456 contains the files x.go and y.go,
-"hg diff @123456" is equivalent to"hg diff x.go y.go".

-# RE: UNICODE STRING HANDLING
-#
-# Python distinguishes between the str (string of bytes)
-# and unicode (string of code points) types.  Most operations
-# work on either one just fine, but some (like regexp matching)
-# require unicode, and others (like write) require str.
-#
-# As befits the language, Python hides the distinction between
-# unicode and str by converting between them silently, but
-# *only* if all the bytes/code points involved are 7-bit ASCII.
-# This means that if you're not careful, your program works
-# fine on "hello, world" and fails on "hello, 世界".  And of course,
-# the obvious way to be careful - use static types - is unavailable.
-# So the only way is trial and error to find where to put explicit
-# conversions.
-#
-# Because more functions do implicit conversion to str (string of bytes)
-# than do implicit conversion to unicode (string of code points),
-# the convention in this module is to represent all text as str,
-# converting to unicode only when calling a unicode-only function
-# and then converting back to str as soon as possible.
-
-def typecheck(s, t):
-	if type(s) != t:
-		raise util.Abort("type check failed: %s has type %s != %s" % (repr(s), type(s), t))
-
-# If we have to pass unicode instead of str, ustr does that conversion clearly.
-def ustr(s):
-	typecheck(s, str)
-	return s.decode("utf-8")
-
-# Even with those, Mercurial still sometimes turns unicode into str
-# and then tries to use it as ascii.  Change Mercurial's default.

-	from mercurial import encoding

-# Even with those we still run into problems.
-# I tried to do things by the book but could not convince
-# Mercurial to let me check in a change with UTF-8 in the
-# CL description or author field, no matter how many conversions
-# between str and unicode I inserted and despite changing the
-# default encoding.  I'm tired of this game, so set the default
-# encoding for all of Python to 'utf-8', not 'ascii'.

-# Change list parsing.

-# Change lists are stored in .hg/codereview/cl.nnnnnn

-# too: the description, reviewer, and cc list are all stored there.
