I've tried symlinking awk to both gawk(4.1.3) and mawk, but I still get the
same error. I'm using Ubuntu 16.04.
Also, I've made the changes in the proposal. Now that I'm aware roughly
about the tasks to be done, I think it's better to stick to either one of
BOT plate mode or BREP support. If time permits, I'll do the other. I'll do
a bit of detailed background study in both cases to check which one should
be plausible in the given time frame and update it in the proposal
accordingly.
