# This script installes (or re-installs) the unit_trace Python module, so that
# the unit_trace library can be imported with `import unit_trace` by a Python
# script, from anywhere on the system.

# The installation merely copies the unit-trace script and the unit_trace
# folder to ~/bin. You can also do this manually if you want to.

# We do not use the Distutils system, provided by Python, because that
# is less convenient :-)
