# The idea is to write a plain text file that can be read easily into
# xml (and hence universally readable).  The name of the block becomes
# the xml tag.  Anything that follows is turned into
# attibutes. e.g. "name ATLAS" inside the block becomes <experiment
# name="ATLAS">.  Anything inside the block starting with "#" becomes
# a comment, i.e. the first block below becomes <analysis
# name="ATLAS" analysis="ATLAS-2014-XXX" cme="8.0" lumi="20.0"
# description="Details about analysis">
# DETECTOROBJ: JET, ELEC, MUON, MET 
# BASE-VARIABLES: PX, PY, PZ, E, PT, ETA, PHI, BETA
# USER-DEFINED VARS: MT(), MT2(), DPHIJMET(J, MET)
