ConMan provides special capabilities (in versions 1.0 and later) that
allow an input stream to be used as a temporary "scratchpad" to store a
series of data lines. These lines can be "stacked" (last in, first out)
or "queued" (first in, first out) to be read at a later time. These
special capabilities are available through the CLI command utilities
PUSH, QUEUE, and DROPBUF. Refer to the PUSH.doc file for further info.
