Release Notes

XLED is an X/Motif based LED server that emulates good old hardware LEDs.
It is implemented on top of the LAM cluster computing environment.  It
provides a low cost alternative for sexy blinking LEDs demos (popular
with supervisors and managers!) and quick-n-dirty debugging.

The XLED client library (libled.a) can be used from all three APIs under
LAM: MPI, PVM, and the low-level interface.  It provides a simple interface
to turn selected LEDs on and off and inquire about their current state.
The user runs XLED on any node in the multicomputer, the library calls
locate and direct their requests to the proper destination.  

We have attempted to make XLED look as uniformly presentable on the six
"UNIX-portable" platforms we support (the same platforms as LAM supports).
The application resource files are meant to fill in the cracks.

XLED works with LAM 5.2 or later.
