1. If there is no XML file the script should grab all the images and put them into
2. /tmp/wikiimages Template:PERL

1. 1) ------------------------------ Get options ------------------------------ #

1. Create tmp subdirectory

1. 2) ---------------- Open input XML file and list of images ------------------ #

1. Not scalable

1. 4) ----------------- Test $imageToMatch against $eachImagePath -------------- #

1. 5) --------------------- Copy subset of wanted images ----------------------- #

foreach my $wantedPath ( @wantedPaths ) {

 chomp($wantedPath);
   
 my $fullPath = $options{'wikiImagePath'} . substr($wantedPath, 1, length $wantedPath); 
 print "$fullPath\n";    
   
 # Copy files
