Looking at the options available in recent versions of WeiDU, it looks like most of things done by the BGT batch files could be done directly in tp2 files. Either directly, for most of the copying, or by calling WeiDU recursively with '--game $BG1PATH' for extracting files for bifs. The only thing that it does seem possible to do directly is call bg2tis and 'weidu --traify-tlk'. Doing this would seem to make it easier to install on linux.
