 Description:
   ' Measurement of gluon jet properties using the jet boost algorithm, a technique to select unbiased samples of gluon jets in $e^+e^-$ annihilation, i.e. gluon jets free of biases introduced by event selection or jet finding criteria.
 Two modes are provided, the prefer option is to produce the fictional $e^+e^-\to g g $  process to be used due to the corrections applied to the data, PROCESS=GG.
 The original analysis technique to extract gluon jets from hadronic $e^+e^-$ events using $e^+e^-\to q\bar{q}$ events, PROCESS=QQ,
 is also provided but cannot be used for tuning as the data has been corrected for impurities, however it is still useful qualitatively in order to check the properties of gluon jets in the original way in which there were measured rather than using a fictitious process.'

 # This Makefile administers the validation for Rivet.
 #
 # Usage: make check
 #
 # For more information use: make help
 #
 # This Makefile was produced by rivet-mkvaldir which scanned all
 # analysis .info files and parsed the "Validation:" section for
 # determining how to use the existing HepMC validation files to obtain
 # a set of reference YODA files that should be reproduced. The
 # direcorey where these reference files are stored is linked to
 # ./refyodas . The HepMC files are stored in ./HEPMC and will be
 # automatically downloaded if missing. In the end of running 'make
 # check', the newly produced YODA files will be compared with the
 # reference ones. If differences are found in any histogram, the
 # corresponing plot will be produced by rivet-mkhtml and can be
 # accessed from the index.html file.
 #
 # The syntax for specifying a reference YODA in the .info file looks
 # as follows:
 #
-#  - YODA-name HEPMC-name [other dependencies] [[; commandline] ...]
+#  - YODA-name HEPMC-name [:option=val] [dependencies] [[; commandline] ...]
 #
 # the YODA-name should be given without the .yoda suffix and typically
 # is constructed from the analysis name with some number appended if
 # there are more than one reference YODA for an analysis. Note that
 # the sting "$A" can be used anywher and will be expanded to the
 # analysis name. HEPMC-name should given without the ".hepmc.gz"
-# suffix. "other dependencies" can eg. include the reference YODA from
+# suffix. "dependencies" can eg. include the reference YODA from
 # another analysis that are referenced in any of the
 # "commandline"s. If no commandline is given the analysis will be run
 # together with a bunch of other analyses and the YODA-name.yoda will
-# be extracted form the resulting yoda. The command lines will be used
-# as make recipes where the output YODA file can be given by $@ and the
-# HepMC file by $<
+# be extracted form the resulting yoda. In this case the analysis will
+# be run using the "options" if present. The command lines will be used
+# as "make" recipes where the output YODA file can be given by $@ and the
+# HepMC file by $< possible options must then be included by explicitly
 #
 # When submitting a new analysis to Rivet, the "Validation:" section
 # of the .info file must be present and all the corresponding YODA
 # reference file should be be included in the submission. If a
 # non-standard HepMC file is needed to reproduce the reference YODA,
 # this must be included as well.
