# Details:
# Compiles (GCC) trampoline/trampoline.c to trampoline/trampoline.
# Creates jail/.
# Creates standard subdirs inside the jail, eg bin, opt, home, tmp.
# 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 files for all the IVLE .py files.
