setup: remove misc/make-version.py and invoke "darcsver" from the pyutil library
misc/make-version.py has a limitation which prevents it from generating version stamps from our current darcs history. This limitation has been fixed in pyutil's "darcsver". Rather than copy the fix from there to misc/make-version.py, I'm making it so that you have to install pyutil if you want to automatically generate _version.py files from the current darcs history.

Create _version.py, based upon the latest darcs release tag.
|
||||
|
||||
If your source tree is coming from darcs (i.e. it is in a darcs repository),
|
||||
this tool will determine the most recent release tag, count the patches that
|
||||
have been applied since then, and compute a version number to be written into
|
||||
_version.py . This version number will be available by doing:
|
||||
|
||||
from your_package_name import __version__
|
||||
|
||||
Source trees that do not come from darcs (e.g. release tarballs, nightly
|
||||
tarballs) and are not within a darcs repository should instead, come with a
|
||||
_version.py that was generated before the tarball was produced. In this case,
|
||||
this script will quietly exit without modifying the existing _version.py .
