I got it installed with pip, but issuing any 'git review' command doesn't work.  I don't *think* it's a path problem, but instead whatever mechanics git-review did to hook itself into git's command parser

Git's command parser appears to be something similar to

	system("git-" || the arguments to git);

where "||" is the concatenation operator (yes, I learned PL/I in my youth; why do you ask? :-)).

I.e., if you do

	git blahblahblah foo bar bletch

it tries to run the command

	git-blahblahblah foo bar bletch

	$ which git-review

	$ file `which git-review`
	/usr/local/bin/git-review: Python script, ASCII text executable

so git-review is just a Python script with a #! header, so that an exec-family call (which includes posix_spawn() on systems, such as newer versions of OS X, that have it) on that file will run the Python interpreter on it.

The only thing I had to do on my Mac, running 10.8.5, was to:

	remove the old copy of pip I'd installed a while ago (as it couldn't handle the current git-review package for some reason);

	installed the latest version of pip;

and then run "pip install git-review".
