Compiles all files and sets up a jail template in the source directory.
-O is recommended to cause compilation to be optimised.
Details:
Compiles (GCC) trampoline/trampoline.c to trampoline/trampoline.
Compiles (GCC) timount/timount.c to timount/timount.
Creates jail with system and student packages installed from MIRROR.
Copies console/ to a location within the jail.
Copies OS programs and files to corresponding locations within the jail
(eg. python and Python libs, ld.so, etc).
Generates .pyc or .pyo files for all the IVLE .py files."""
