# i3status-value <state> <key> (module i3status-rust, novox/hq ADR 0260): one value another module keeps
# on the bus, for a block it contributed.
#
# This module's own tools bundle watches the state on the bus (the mesh grants it the read) and leaves
# the value's text in this module's own directory; this prints it. A value not refreshed for thirty
# seconds is one its module stopped giving, and prints nothing, so the block hides rather than show an
# old number as if it were now.
