# A queue to be used for communicating information from a spoke back to its
|
|
# hub. This information includes things like marking spokes as ready and
|
|
# updating the status line to tell the user why a spoke is not yet available.
|
|
# This queue should have elements of the following format pushed into it:
|
|
#
|
|
# (HUB_CODE_*, [arguments])
|
|
#
|
|
# Arguments vary based on the code given, but the first argument must always
|
|
# be the name of the class of the spoke to be acted upon. See below for more
|
|
# details.
