+=head1 NAME
+
+dh_installexamples - install example files into package build directories
+
+=cut
+
+use strict;
 use Debian::Debhelper::Dh_Lib;
+
+=head1 SYNOPSIS
+
+B<dh_installexamples> [S<I<debhelper options>>] [B<-A>] [B<-X>I<item>] [S<I<file ...>>]
+
+=head1 DESCRIPTION
+
+dh_installexamples is a debhelper program that is responsible for
+installing examples into usr/share/doc/package/examples in package
+build directories.
+
+Any file names specified as parameters will be installed into the first
+package dh_installexamples is told to act on. By default, this is the first
+binary package in debian/control, but if you use -p, -i, or -a flags, it
+will be the first package specified by those flags.
+
+Files named debian/package.examples can list other files to be installed.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-A>, B<--all>
+
+Install any files specified by command line parameters in ALL packages
+acted on.
+
+=item I<file ...>
+
+Install these files as examples into the first package acted on. (Or into
+all packages if -A is specified.)
+
+=item B<-Xitem>, B<--exclude=item>
+
+Exclude files that contain "item" anywhere in their filename from
+being installed.
+

+
+=head1 NOTES
+
+Note that dh_installexamples will happily copy entire directory hierarchies
+if you ask it to (similar to cp -a). If it is asked to install a
+directory, it will install the complete contents of the directory.
