+# mcl_buckets
+Add an API to register buckets to mcl
+
+## mcl_buckets.register_liquid(def)
+
+Register a new liquid
+Accept folowing params:
+* source_place = a string or function.
+	* string: name of the node to place
+	* function(pos): will returns name of the node to place with pos being the placement position
+* source_take = table of liquid source node names to take
+* itemname = itemstring of the new bucket item (or nil if liquid is not takeable)
+* inventory_image = texture of the new bucket item (ignored if itemname == nil)
+* name = user-visible bucket description
+* longdesc = long explanatory description (for help)
+* usagehelp = short usage explanation (for help)
+* tt_help = very short tooltip help
+* extra_check(pos, placer) = optional function(pos) which can returns false to avoid placing the liquid. Placer is object/player who is placing the liquid, can be nil.
+* groups = optional list of item groups
+
+This function can be called from any mod (which depends on this one)
