-# In order to prevent environment pollution, the output of this script
-# is a list of commands which must be sourced. This can be achieved
-# through a simple shell function:
-#
-#     rbpm() { source <(/path/to/rbpm.sh "${@}"); }
-#
-# Placing the above function inside ~/.bashrc (or equivalent) will load
-# it upon starting your shell.
