+Hang Glider Mod for Minetest
+----------------------------
+This is a fork of the minetest-hangglider mod by Piezo_ (orderofthefourthwall@gmail.com)
+
+Which is located at:
+ <https://notabug.org/Piezo_/minetest-hangglider>
+
+**This version is an experimental version that is not intended for general use.**
+
+It includes the following changes by David G (kestral246@gmail.com):
+
+- Give visual indication that hangglider is equiped.
+ - Display simple overlay with blurred struts when equiped.
+ - Issue: don't know how to disable overlay when using third person view.
+
+- Also unequip hangglider when landing on water.
+
+- Attempt to linearize parabolic flight path.
+ - Start gravity stronger, but gradually reduce it as descent velocity increases.
+ - Don't use airstopper when equipped from the ground (descent velocity is low).
+ - Slightly increase flight speed to 1.25.
+
+- Unequip/equip cycling mid-flight should not fly farther than continuous flight.
+ - When equipping mid-air (descent velocity higher), use airstopper but increase descent slope afterwards.
+ - Create airbreak flag so all equips mid-flight use faster descent.
+ - Reset airbreak flag only when land (canExist goes false).
+ - Issue: it wouldn't reset if land in water, use fly, and launch from air, before I added test for water,
+ - Not sure if there are other such cases.
+
+- Did another round of parameter tuning.
+ - Commented out hud debug display code with prefix "--debug:".
+
+- For Minetest 5.x the glider's set_attach point needs to be offset by 1 node.
+ - Provided alternate commented out version of this line that has the correct offset.
+
+- Discovered that sprint mod interferes with this mod's speed settings.
+ - It's likely that other mods that affect player_physics will have this same problem.
+ - May need to consider adding player_monoid support to this mod.
