+=head1 SYNOPSIS
+
+B<dh_fixperms> [S<I<debhelper options>>] [B<-X>I<item>]
+
+=head1 DESCRIPTION
+
+B<dh_fixperms> is a debhelper program that is responsible for setting the
+permissions of files and directories in package build directories to a
+sane state -- a state that complies with Debian policy.
+
+B<dh_fixperms> makes all files in F<usr/share/doc> in the package
+build directory (excluding files in the F<examples/> directory) be
+mode 644. It also changes the permissions of all man pages to mode
+644. It removes group and other write permission from all files. It
+removes execute permissions from any libraries, headers, Perl modules,
+or desktop files that have it set. It makes all files in the standard
+F<bin> and F<sbin> directories, F<usr/games/> and F<etc/init.d>
+executable (since v4). Finally, it removes the setuid and setgid bits
+from all files in the package.
+
+When the I<Rules-Requires-Root> field has the (effective) value of
+I<binary-targets>, B<dh_fixperms> will also reset the ownership of
+all paths to "root:root".
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-X>I<item>, B<--exclude> I<item>
+
+Exclude files that contain I<item> anywhere in their filename from having
+their permissions changed. You may use this option multiple times to build
+up a list of things to exclude.
