This is an example of how to take an Ikiwiki setup file and mangle it
programmatically. In my case, I'm running it on the fly for use with
`| sudo -u ikiwiki ikiwiki --setup - --refresh --verbose` in order to strip out
the cgi-related functions. In the future, I think it would be better to have dev and live on different git branches and have one Ikiwiki setup for each.

    use Data::Dumper qw( );
    
    sub import {
      my ( $class, $config ) = @_;
    
    #  foreach my $key ( grep { /^[^aeiou]/i } keys %{$config} ) {
    #    delete $config->{$key};

      delete $config->{cgiurl};

      delete $config->{historyurl};
      delete $config->{wrappers};
    
      # delete cgi-relevant plugins
      @{$config->{add_plugins}} = grep(!/^(wmd|httpauth|attachment|rename|remove|search)$/, @{$config->{add_plugins}});
    
      push(@{$config->{disable_plugins}}, 'recentchanges');
