some questions about AngelScript, if anyone used it

[heepoo]

hi all,
i'm developing a game engine for visually impaired users (firstly myself), to help them develop audio games
this application is open-source and i want to use AngelScript
now the questions are, firstly, how can i use angelscript's bytecode compiler and asCJIT compiler? i want to run void main() function, but it can't run it!
secondly, how can i create a run function for people to allow them to run there scripts
thanks in advance
