help: replace some str.split() calls by str.partition() or str.rpartition()
Since Python 2.5 str has new methods: partition and rpartition. They are more
specialized than the usual split and rsplit, and they sometimes convey the
intent of code better and also are a bit faster (faster than split/rsplit with
maxsplit specified). Let's use them in appropriate places for a small speedup.
Example performance (partition):
$ python -m timeit 'assert "apple|orange|banana".split("|")[0] == "apple"'
1000000 loops, best of 3: 0.376 usec per loop
$ python -m timeit 'assert "apple|orange|banana".split("|", 1)[0] == "apple"'
1000000 loops, best of 3: 0.327 usec per loop
$ python -m timeit 'assert "apple|orange|banana".partition("|")[0] == "apple"'
1000000 loops, best of 3: 0.214 usec per loop
Example performance (rpartition):
$ python -m timeit 'assert "apple|orange|banana".rsplit("|")[-1] == "banana"'
1000000 loops, best of 3: 0.372 usec per loop
$ python -m timeit 'assert "apple|orange|banana".rsplit("|", 1)[-1] == "banana"'
1000000 loops, best of 3: 0.332 usec per loop
$ python -m timeit 'assert "apple|orange|banana".rpartition("|")[-1] == "banana"'
1000000 loops, best of 3: 0.219 usec per loop

WiX installer source files ========================== The files in this folder are used by the thg-winbuild [1] package building architecture to create a Mercurial MSI installer. These files are versioned within the Mercurial source tree because the WXS files must kept up to date with distribution changes within their branch. In other words, the default branch WXS files are expected to diverge from the stable branch WXS files. Storing them within the same repository is the only sane way to keep the source tree and the installer in sync. The MSI installer builder uses only the mercurial.ini file from the contrib/win32 folder, the contents of which have been historically used to create an InnoSetup based installer. The rest of the files there are ignored. The MSI packages built by thg-winbuild require elevated (admin) privileges to be installed due to the installation of MSVC CRT libraries under the C:\WINDOWS\WinSxS folder. Thus the InnoSetup installers may still be useful to some users. To build your own MSI packages, clone the thg-winbuild [1] repository and follow the README.txt [2] instructions closely. There are fewer prerequisites for a WiX [3] installer than an InnoSetup installer, but they are more specific.
