+ ```sh
+ make long-check
+ ```
+
+ or if you're in a bit more of a hurry:
+
+ ```sh
+ make check
+ ```
+
+ If you have the Python xdist module installed, then you can
+ probably run the tests faster by adding the make -j option (see <a
+ href="HACKING">./HACKING</a> for additional information):
+
+ ```sh
+ make -j check
+ ```
+
+ The tests should pass. If they don't pass for you, stop here and
+ send an email to bup-list@googlegroups.com. Though if there are
+ symbolic links along the current working directory path, the tests
+ may fail. Running something like this before "make test" should
+ sidestep the problem:
+
+ ```sh
+ cd "$(pwd -P)"
+ ```
+
+ - You can install bup via "make install", and override the default
+ destination with DESTDIR and PREFIX.
+
+ Files are normally installed to "$DESTDIR/$PREFIX" where DESTDIR is
+ empty by default, and PREFIX is set to /usr/local. So if you wanted to
+ install bup to /opt/bup, you might do something like this:
+
+ ```sh
+ make install DESTDIR=/opt/bup PREFIX=''
+ ```
+
+ - The Python version that bup will use is determined by the
+ `python-config` program chosen by `./configure`, which will search
+ for a reasonable version unless `BUP_PYTHON_CONFIG` is set in the
+ environment. You can see which Python executable was chosen by
+ looking at the configure output, or examining
+ `config/config.var/bup-python-config`, and you can change the
+ selection by re-running `./configure`.
