The latter would create +F<< /usr/share/doc/I<package>/examples/examples >>, which is rarely what you want. + +Supports substitution variables in compat 13 and later as +documented in L<debhelper(7)>. + +=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<--sourcedir=>I<dir> + +Look in the specified directory for files to be installed. This option +requires compat 11 or later (it is silently ignored in compat 10 or earlier). + +Note that this is not the same as the B<--sourcedirectory> option used +by the B<dh_auto_>I<*> commands. You rarely need to use this option, since +B<dh_installexamples> automatically looks for files in F<debian/tmp> in debhelper +compatibility level 11 and above. + +=item B<--doc-main-package=>I<main-package> + +Set the main package for a documentation package. This is used to +install the documentation of the documentation package in F<< +/usr/share/doc/I<main-package> >> as recommended by the Debian policy +manual 3.9.7 in ยง12.3. + +In compat 11 (or later), this option is only useful if debhelper's +auto-detection of the main package is wrong. The option can also be +used to silence a warning from debhelper when the auto-detection fails +but the default happens to be correct. + +This option cannot be used when B<dh_installexamples> is instructed to act +on multiple packages. If you need this option, you will generally +need to combine it with B<-p> to ensure exactly one package is 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.
