# Marble is a dual FMC FPGA carrier board developed for general purpose use in
# particle accelerator electronics instrumentation. It is currently under
# development and the base platform for two accelerator projects at DOE: ALS-U
# (the Advanced Light Source Upgrade at LBNL and the LCLS-II HE (the Linac
# Coherent Light Source II High Energy upgrade).
