"""%prog

Script for merging parts of multiple histo files made with different run params
(kinematic pT cuts and energies) into one histo file for plotting or further
analysis.

TODO:
 * take merge specs from a conf file instead of hard-coding
 * generalise to more generic merge ranges (i.e. not just sqrts & pT)
 * improve cmd line interface
 * rationalise all histogramming formats... remove AIDA!
 * use lighthisto (then YODA)

Usage example:
 $ uemerge hwpp/hpp-1800-{030.aida:1800:30,090.aida:1800:90} > hpp-hists.dat
 $ flat2aida hpp-hists.dat
 $ mkdir plots && cd plots
 $ compare_histos.py ../ref04.aida ../hpp-hists.aida
 $ make_plot.py --pdf *.dat
