+=head1 SYNOPSIS
+
+B<dh_usrlocal> [S<I<debhelper options>>] [B<-n>]
+
+=head1 DESCRIPTION
+
+B<dh_usrlocal> is a debhelper program that can be used for building packages
+that will provide a subdirectory in F</usr/local> when installed.
+
+It finds subdirectories of F<usr/local> in the package build directory, and
+removes them, replacing them with maintainer script snippets (unless B<-n>
+is used) to create the directories at install time, and remove them when
+the package is removed, in a manner compliant with Debian policy. These
+snippets are inserted into the maintainer scripts by B<dh_installdeb>. See
+L<dh_installdeb(1)> for an explanation of debhelper maintainer script
+snippets.
+
+When the I<DEB_RULES_REQUIRES_ROOT> environment variable is not (effectively)
+I<binary-targets>, the directories in F</usr/local> will be handled as if
+they were owned by root:root (see below).
+
+When the I<DEB_RULES_REQUIRES_ROOT> environment variable has an effective value of
+I<binary-targets>, the owners, groups and permissions will be
+preserved with the sole exception where the directory is owned by root:root.
+
+If a directory is owned by root:root, then ownership will be determined
+at install time.  The ownership and permission bits will either be root:root
+mode 0755 or root:staff mode 02775.  The actual choice depends on whether
+the system has F</etc/staff-group-for-usr-local> (as documented in the Debian
+Policy Manual §9.1.2 since version 4.1.4)
+

+=head1 NOTES
+
+Note that this command is not idempotent. L<dh_prep(1)> should be called
+between invocations of this command. Otherwise, it may cause multiple
+instances of the same text to be added to maintainer scripts.
