+=head1 SYNOPSIS
+
+B<dh_runit> [S<I<debhelper options>>] [B<--no-enable>]
+
+=head1 DESCRIPTION
+
+B<dh_runit> is a debhelper program that is responsible for
+installing and enabling I<runit> runscripts. If file named
+F<debian/I<package>.runit> exists, then different actions
+are performed, depending on its format.
+
+For runit, every unit of supervision, simply speaking program, is
+represented by directory under F</etc/sv>, containing at least F<run>
+executable file. Every enabled program is represented by symbolic link
+under F</etc/services> pointing to some directory under F</etc/sv>.
+
+If F<debian/I<package>.runit> is not executable, but contains shebang
+(#!) in first line, it is installed as F</etc/sv/I<package>/run> and
+enabled.
+
+Alternatively, F<debian/I<package>.runit> is a list of lines, where
+every line is either starts with hash symbol and considered comment,
+or contains two or three space-separated words.
+
+  # In this case file is installed as 'run' script. Directory name under
+  # /etc/sv is derived from file basename
+  enable path/to/file/to/be/installed/as/run/script
+
+  # Same, but install directory as whole. It is your responsibility
+  # to ensure is contains everything required.
+  enable path/to/directory
+
+  # Same as above, but do not create symlink under /etc/service
+  disable path/to/directory
+
+  # Also, you can explicitly specify name of directory under /etc/sv
+  enable path/to/directory my-preferred-name
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<--no-enable>
+
+Do not enable any runscripts. Useful, when F<debian/I<package>.runit>
+is the only runscript, in which case you have no other ways to
+specify, that it should not be enabled.
