HOW TO INSTALL git-subtree
==========================
First, build from the top source directory.
Then, in contrib/subtree, run:
make
make install
make install-doc
If you used configure to do the main build the git-subtree build will
pick up those settings. If not, you will likely have to provide a
value for prefix:
make prefix=<some dir>
make prefix=<some dir> install
make prefix=<some dir> install-doc
To run tests first copy git-subtree to the main build area so the
newly-built git can find it:
cp git-subtree ../..
Then:
make test
