I added another powwow command #mud. Without arguments it just invokes the Mudlle interpreter. With "filename" as argument it initially loaded the given mudlle script and executed it. But that would mean that everytime #mud is used, the given mudlle code would be reloaded, also it would always start executing at the beginning of the file.
So I recoded it, so that the #mud interprets its arguments as mudlle code. That way you can just specify a loaded function to be executed. e.g. #mud group_add() You have to make sure that the mudlle libraries, which you want to use have been loaded.
e.g. #mud load ("dlist.mud"); etc...
In any case all current powwow variables are imported into the mudlle environment. Eventually I will add some powwow_import(varname) function, but for now it has to work as it is. (@0..@9 are not imported, all other variables are. The $ as prefix is cut away. Variables starting with a number will be prefixed by "p".
Variables are NOT exported back to powwow. I hardcoded a mudlle function powwow_exec(), which will execute any powwow command. So you can do stuff like powwow_exec ("#var $axel=1")
