# cli_checkPathComponent.sh -- This function checks parts/components
# from repository paths. Generally, the path information is passed to
# the function's first positional argument and the part/component we
# want to check is passed to the function's second positional
# argument. If the second argument is not passed, then the first
# argument is assumed to be the part/component we want to check, and
# the action value (ACTIONVAL) variable is used instead as source path
# information.
