=head1 Checklist

(and a short version for the impatient):

=head2 Commits:

=over 4

=item * make commits of logical units

=item * check for unnecessary whitespace with "git diff --check" before committing

=item * do not check in commented out code or unneeded files

=item * the first line of the commit message should be a short description and
should skip the full stop

=item * the body should provide a meaningful commit message, which:

=over 4

=item * uses the imperative, present tense: "change", not "changed" or "changes".

=item * includes motivation for the change, and contrasts its implementation with
previous behaviour

=back

=item * if you want your work included in the main repository, add a "Signed-off-by:
Your Name <you@example.com>" line to the commit message (or just use the
option "-s" when committing) to confirm that you agree to the Developer's
Certificate of Origin

=item * make sure that you have tests for the bug you are fixing

=item * make sure that the test suite passes after your commit

=back

=head2 Patch:

=over 4

=item * use "git format-patch -M" to create the patch

=item * do not PGP sign your patch

=item * be careful doing cut & paste, not to corrupt whitespaces.

=item * provide additional information (which is unsuitable for the commit
message) between the "---" and the diffstat

=item * if you change, add, or remove any features or make some other user
interface change, the associated documentation should be updated as well.

=item * if your name is not writable in ASCII, make sure that you send the
patch in the correct encoding.

=head1 Long version:

I started reading over the SubmittingPatches document for git,
primarily because I wanted to have a document similar to it for
my projects to make sure people understand what they are doing
when they write "Signed-off-by" line.

But the patch submission requirements are a lot more relaxed
here on the technical/contents front, because my projects are
thousand times smaller ;-).  So here is only the relevant bits.

=head2 (0) Decide what to base your work on.

In general, always base your work on the oldest branch that your
change is relevant to.

=over 4

=item * A bugfix should be based on 'maint' in general. If the bug is not
present in 'maint', base it on 'master'. For a bug that's not yet
in 'master', find the topic that introduces the regression, and
base your work on the tip of the topic.

=item * A new feature should be based on 'master' in general. If the new
feature depends on a topic that is in 'pu', but not in 'master', base your
work on the tip of that topic.

=item * Corrections and enhancements to a topic not yet in 'master' should be
based on the tip of that topic. If the topic has not been merged to 'next',
it's alright to add a note to squash minor corrections into the series.

=item * In the exceptional case that a new feature depends on several topics
not in 'master', start working on 'next' or 'pu' privately and send out
patches for discussion. Before the final merge, you may have to wait until
some of the dependent topics graduate to 'master', and rebase your work.

=back

To find the tip of a topic branch, run "git log --first-parent
master..pu" and look for the merge commit. The second parent of this
commit is the tip of the topic branch.

=head2 (1) Make separate commits for logically separate changes.

Unless your patch is really trivial, you should not be sending
out a patch that was generated between your working tree and
your commit head.  Instead, always make a commit with complete
commit message and generate a series of patches from your
repository.  It is a good discipline.

Describe the technical detail of the change(s).

If your description starts to get too long, that's a sign that you
probably need to split up your commit to finer grained pieces.
