+=item B<--parallel>
+
+Enable parallel builds if underlying build system supports them.
+The number of parallel jobs is controlled by the
+DEB_BUILD_OPTIONS environment variable (L<Debian Policy, section 4.9.1>) at
+build time. It might also be subject to a build system specific limit.
+
+If this option is not specified, debhelper currently defaults to not
+allowing parallel package builds.
+
+=item B<--max-parallel>I<=maximum>
+
+This option implies L<--parallel> and allows further limiting the number of
+jobs that can be used in a parallel build. If the package build is known to
+only work with certain levels of concurrency, you can set this to the maximum
+level that is known to work, or that you wish to support.
