+--[[About this plugin
+This plugin adds the module "OpenInExplorer" to darktable's lighttable view
+
+----REQUIRED SOFTWARE----
+Microsoft Windows or Linux with installed Nautilus
+
+----USAGE----
+Install: (see here for more detail: https://github.com/darktable-org/lua-scripts )
+ 1) Copy this file in to your "lua/contrib" folder where all other scripts reside. 
+ 2) Require this file in your luarc file, as with any other dt plug-in
+
+Select the photo(s) you wish to find in explorer and press "Go to Folder". 
+A file explorer window will be opened for each selected file at the file's location; the file will be highlighted.
+
+----KNOWN ISSUES----
+Under macOS the file manager Finder opens only once and selects the file name of the last in DT selected image.
