need help how to use global AI & lua UI

[BrainDamage]

hello, i've done a a quick search trought the forums & in the wiki (the wiki pages were blank or not-existant), so i'm asking here

how to enable the LUA UI and how to use an global AI?

i do have placed both in the correct folders, but now i'd like to know how to turn them on in the game (eg. turn on metal-maker AI; or how to assign the moho mine auto-upgrade to builders)

ps. if it matters i'm using spring under linux (yes, the files are correctly placed in my R-W directory)

thanks in advance
