Adding dynamic y-tick placement and bundling the ChangeLog in the tarball. Release 1.2.2

andy@8 3 """\
andy@8 4 A simple but flexible parser of SUSY Les Houches Accord (SLHA) model and decay files.
andy@25 5
andy@52 6 pyslha is a parser/writer module for particle physics SUSY Les Houches Accord
andy@52 7 (SLHA) supersymmetric spectrum/decay files, and a collection of scripts which
andy@52 8 use the interface, e.g. for conversion to and from the legacy ISAWIG format, or
andy@52 9 to plot the mass spectrum and decay chains.
andy@52 10
andy@52 11 The current release supports SLHA version 1. Assistance with supporting version
andy@52 12 2 will be gladly accepted!
andy@52 13
andy@131 14 The plotting script provides output in PDF, EPS and PNG via LaTeX and the TikZ
andy@131 15 graphics package, and as LaTeX/TikZ source for direct embedding into documents or
andy@131 16 user-tweaking of the generated output.
andy@64 17
andy@52 18 TODOs:
andy@64 19 * Identify HERWIG decay matrix element to use in ISAWIG
andy@52 20 * Split writeSLHA into writeSLHA{Blocks,Decays}
andy@52 21 * Handle SLHA2
andy@52 22 * Handle RPV SUSY in ISAWIG
