+=head1 Commit check
+
+This is a simple commit style checker. It is made to be used as a git
+C<commit-msg> hook. It expects the name of the file to check as the
+first command-line argument. The style that's checked is based on
+tpope's L<A Note About Git Commit
+Messages|http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html>.
+
+=head2 Command-line options
+
+There are 2 command line options available for use with this program:
+
+=over
+
+=item -0
+
+Don't return a non-zero status when errors have been found. For use as
+a git C<commit-msg> hook it is important that it does exit with a
+non-zero status. But if you are using it for other tools, such as for
+a flycheck checker, exiting with a non-zero status might confuse the
+tools calling it.
+
+=item -h
+
+Show a little help text that describes the command line options and
+usage.
+
+=back
+
+When no arguments are passed (not even the file name) the help text is
+also shown and the exit status is non-0 (no matter if C<-0> has been
+given).
+
+=head2 Errors
+
+Currently there are 5 style errors that are checked for.
+
+=over
+
+=item 1
+
+The first character of the first line of the commit message should be
+capitalized.
+
+=item 2
+
+The first line of the commit message should be no longer than 50
+characters.
+
+=item 3
+
+The first line of the commit message should not end with a period.
+
+=item 4
+
+The second line of the commit message should be empty.
+
+=item 5
+
+No line should be longer than 72 characters.
+
+=back
+
+All comments are skipped and so is all whitespace at the beginning of
+the file.
+
+If any of the error conditions are encountered, and the C<-0> option
+has not been given, the program will exit with a non-C<0> status. This
+has the effect of stopping git from committing the message when this
+program is used as a C<commit-msg> hook. Each error condition
+encountered also prints a message to the standard error stream.
