This script does two things:
When on the spokensanskrit.org site, it adds links to sanskrit.inria.fr site for noun and verb lookup (a small right pointing triangle will appear).
When on other sites, a toolbar with buttons to Sanskrit-related resources is shown. The toolbar can be hidden/shown by clicking on the Sanskrit 'sa' icon at the bottom right of the screen. The toolbar contains links to: daily sanskrit news from India, online Sanskrit magazines, Wikipedia, and grammatical tools (dictionary, verb/noun declinations, sandhi joiner). Works on browsers that support userscripts (such as Firefox, Chrome).
Options (shown in the toolbar):
Auto-dictionary: If enabled, double clicking any word in the window pane will launch the dictionary window with this word.
