# purpose: the schema event.xsd and create the two files hits.xml
#          and reaction.xml using schema-hddm
#
# Note:    in order for this script to work schema-hddm and schema-hddm.xsl
#          are needed. Best run this script in ${HALLD_HOME}/src/programs/Utilities/hddm
#          and copy the two output xml files to ${HALLD_HOME}/src/libraries/HDDM/
