+# === HWMAP-to-Lua converter ===
+# This script allows you to put arbitrary HWMAPs into your missions!
+#
+# Usage:
+# It expects a .hwmap file of name "map.hwmap" to be in
+# its directory and creates a Lua file (map.lua) containing code to
+# draw the map.
+# In Lua, call drawMap() in onGameInit. And don't forget
+# to set MapGen to mgDrawn. Then your map should be ready to go! :-)
+#
+# Many thanks to szczur!
