# useful targets:
#   make sdist ---------------- produce a tarball
#   make rpm  ----------------- produce RPMs
#   make docs ----------------- rebuild the manpages (results are checked in)
#   make pyflakes, make pycodestyle -- source code checks
#   make test ----------------- run all unit tests (export LOG=true for /tmp/ logging)

# Normal setting of a variable - values within it are recursively

# > VARIABLE := value
#
# Setting of a variable with simple expansion of the values inside -
