+Minetest Game mod: XPFW
+==========================
+See license.txt for license information.
+
+XPFW provide an API for storing values relevant for experience mechanism into player metadata. It also stores several statistic values during playtime:
+- Walked distances calculated out of velocity (important: teleporting does not influence this value)
+- accumulated distance out of comparing with last known position (important: teleporting is included in this value)
+- whole playtime on the server
+- amount of dug nodes
+- amount of build nodes
+- amount of crafted items
+- amount of occured deahts
+- amount of text messages
+- amount of logins
+
+For several amounts also a kind of speed is calculated, like walking speed or crafting speed.
