# setup/build.py

# Compiles all files and sets up a jail template in the source directory.

# 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.
