# Commentary
# -----------------------------------------------------------------------------
# This is the builder script for the Serene project. It makes it easier to
# interact with the CMake build scripts.
#
# In order to define a subcommand all you need to do is to define a function
# with the following syntax:
#
# function subcommand-name() { ## DESCRIPTION
#   .. subcommand body ..
# }
#
# Make sure to provid one line of DESCRIPTION for the subcommand and use two "#"
# characters to start the description following by a space. Otherwise, your
# subcommand won't be registered
