=head1 SYNOPSIS

  dh_installexamples [debhelper options] [-A] [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.)

=back

=head1 NOTES

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