     2 # === HWMAP-to-Lua converter ===

     3 # This script allows you to put arbitrary HWMAPs into your missions!

     4 #

     5 # Usage:

     6 # It expects a .hwmap file of name "map.hwmap" to be in

     7 # its directory and creates a Lua file (map.lua) containing code to

     8 # draw the map.

     9 # In Lua, call drawMap() in onGameInit. And don't forget

    10 # to set MapGen to mgDrawn. Then your map should be ready to go! :-)
