JSLIB_URL	/javascript/	

links to JS files are in the ../templates/*.html files

but _also_, and peculiarly, in the troggle/admin.py files (which are dead links)
i.e.
class TroggleModelAdmin(admin.ModelAdmin):
    
    def save_model(self, request, obj, form, change):
        """overriding admin save to fill the new_since parsing_field"""
        obj.new_since_parsing=True
        obj.save()
    
    class Media:
        js = ('jquery/jquery.min.js','js/QM_helper.js')

NB any *Admin class is used in the Django control panel only.

The jquery links have been REMOVED from the templates as they were not used anywhere.
