#                 1. DEPENDANCIES                     #
#######################################################

##############################
#          1.a FILES         #
##############################
Need access to newest of the following files (which
should already be in the MyAnalysis svn):
  MyBand.{cxx,h}         - Does PDF(s) overlay & ratio drawing
  MyCrossSection.{cxx,h} - Deals with other classes & draws frame
  MyData.{cxx,h}         - Reads & holds MyData steering info
  MyEvent.{cxx,h}        - Holds event details
  MyFrame.{cxx,h}        - The framewith anoverlay & ratio section
  MyFrameData.{cxx,h}
  MyGrid.{cxx,h}         - home for Applgrid inforamtion
  MyPDF.{cxx,h}          - Holds PDF inforamtion
  MyGrids/               - Directory for holding APPLGrids 
  MyPDF/                 - Directory holding MyPDF steerings

These code and directories are needed for the 
MyAnalysis framework. The MyGrids directory is not
'needed' because you can place your applegrids 
wherever you want in the project directory, so long
as the MyGrid steering path is correct.


##############################
#        1.b SOFTWARE        #
##############################
Also needed is the following software:
  hoppet   - 1.1.6
  applgrid - Any version (recommend 1.4.56 )
  root     - A version  <= v5.34.18
  LHAPDF   - 5.9.1 (avoid > 6 for now b/c of PDF directory changes)

The above code is needed because Hoppet is used by Applgrid, 
LHAPDF houses the PDF code and files, and everyone needed ROOT.

This software can be downloaded by doing each of the following as commands in Terminal:
  svn checkout http://hoppet.hepforge.org/svn/trunk hoppet
  wget http://www.hepforge.org/archive/applgrid/applgrid-1.4.56.tgz
  wget ftp://root.cern.ch/root/root_v5.34.20.source.tar.gz
  wget http://www.hepforge.org/archive/lhapdf/lhapdf-5.9.1.tar.gz

Also needed is to link a PDFsets directory to the home project 
directory. Either link to the one provided in the lhapdf-config 
path, like so:

  ln -s `lhapdf-config --pdfsets-path`

You can also link your own PDFsets directory:

  ln -s <some/path/PDFsets> .


##############################
#        1.c STEERING        #
##############################
The MyAnalysis code also uses steering file to run 
examples can be found in the the 'example' directory.

A MyCrossSection steering file requires a MyGrid 
steering, MyPDF steering, and MyGrid steering. 
examples of steering files for these can be found in 
the 'docs' directory



#######################################################
#                      2. SETUP                       #
#######################################################

##############################
#  2.a INSTALL DEPENDANCIES  #
##############################
First install all dependant software, which can all
be found in the above DEPENDANCES section 2.b.


##############################
#  2.b UPDATE SETUP SCRIPT   # 
##############################
Edit the setup script called 'setuplxplus.sh' to your 
liking, and then perform:

  source setuplxplus.sh
  make clean
  make



#######################################################
#                     3. RUNNING                      #
#######################################################
Executable 'plot' which us generated after a 'make' 
takes only one parameter, a MyCrossSection steering 
file.

Make your own steering files in the format that can
be found in the 'docs' directory. Examples is also 
found in the 'example' directory.

Output from running will show in root, so you should
enable X11 forwarding if you are ssh'ing in, which 
for cern lxplus user's looks something like:

  ssh -X username@lxplus.cern.ch



####################################################
#               4. EXAMPLE RUNS                    #
####################################################
EXAMPLE RUN(S):

Consider the example in the example directory that
can be ran with:

  ./plot example/atlastest.txt
