=head1 NAME
dh_installexamples - install example files into package build directories
=cut

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
B<dh_installexamples> is a debhelper program that is responsible for
installing examples into F<usr/share/doc/package/examples> in package
build directories.
=head1 FILES
=over 4
=item debian/I<package>.examples
Lists example files or directories to be installed.
=back
=head1 OPTIONS
=over 4
=item B<-A>, B<--all>
Install any files specified by command line parameters in ALL packages
acted on.
=item B<-X>I<item>, B<--exclude=>I<item>
Exclude files that contain I<item> anywhere in their filename from
being installed.
=item I<file> ...
Install these files (or directories) as examples into the first package
acted on. (Or into all packages if B<-A> is specified.)
=back
=head1 NOTES
Note that B<dh_installexamples> will happily copy entire directory hierarchies
if you ask it to (similar to B<cp -a>). If it is asked to install a
directory, it will install the complete contents of the directory.
