+Digilines Advanced Touchscreen
+==============================
+
+This is the advanced touchscreen from digistuff. mt-mods removed it when they
+took over maintenance, so here it is again as a standalone mod.
+
+Once a channel is set, simply send a raw formspec to it to display it.
+Fields are sent back on the same channel when the form is interacted with.
+
+Use the "lock" element to control who can interact with the form:
+
+* lock[1] - Only users with access to the area can submit the form
+* lock[0] - Anyone can submit the form
