What I did to track elua:

$ git svn clone svn://svn.berlios.de/elua/trunk
$ cd trunk
$ git branch lpc2134
$ git checkout lpc2134
<hack away>
$ git remote upload git@github.com:andreas23/elua-lpc2134.git
$ git push upload lpc2134


How I build my image:

$ scons target=lualong board=tk102-2 cpumode=thumb allocator=simple prog

and then load:

$ lpc21ipc -term elua_lualong_lpc2134.hex /dev/ttyUSB0 57600 11059
