-  * A standalone C++ class, that puts the decay-string in a formatted LaTeX-table. +  * BGlatex: A standalone C++ class, that puts the decay-string in a formatted LaTeX-table. 
-  * A standalone C++ class, that converts the Monte Carlo particle numbers in a LaTeX-string with the particle name.+  * convPDGnumber: A standalone C++ class, that converts the Monte Carlo particle numbers in a LaTeX-string with the particle name.
  
 ===== DaVinci Algorithm BGCat ===== ===== DaVinci Algorithm BGCat =====

   * Type ''make''. Some warnings about deprecated headers will appear.   * Type ''make''. Some warnings about deprecated headers will appear.
   * After it is finished, you should have a **libToolClasses.so** shared object in the folder ''/lib''.   * After it is finished, you should have a **libToolClasses.so** shared object in the folder ''/lib''.
 +  * Copy the **BG_cat.txt** of the DaVinci Algorithm in this directory. This is not absolutely necessary, but makes it a bit easier.
  
 +===== The makeTable()-method =====
 +The class BGlatex has the main method **makeTable()**. It takes five arguments:
 +  *The input file name. Default is: BG_cat.txt
 +  *The output file name. Defaul is: BG_cat.tex
 +  *The numbers of decays per table. This will create a second, third table after a certain amount of decays in the table, and prevents LaTeX from spreading the table over the bottom of the page. Default is: 15
 +  *The number of characters per line. This will create a second, third row in the table after a certain amount of characters per line, and prevents LaTeX from spreading the table of the right margin of the page. Default is: 20
 +  *Full LaTeX header. Choose true if you want to use the table standalone, false if you want to use it via ''/input'' in your LaTeX-document. Default is true.
  
 +==== Notes ====
 +At this moment (09/01/14), all anti-particle numbers are converted into particle numbers.
  
 +===== The PDGlatex()-method =====
 +The class convPDGnumber has the main method **PDGlatex()**, takes as an argument the Monte Carlo number and returns a string with the LaTeX-expression. This method is called internally by **makeTable()**.
 +
 +==== Notes ====
 +At this moment (09/01/14), no anti-particles are implemented.
 +
 +===== How to use it in ROOT/C++ =====
 +The classes have been tested to work with ROOT. To use them, start ROOT and type:
 +  *''gSystem->Load("lib/libToolClasses.so")''
 +  *''BGlatex a''
 +  *''a.makeTable()'' (or with arguments)
 +  *''.q''
 +This should have created a file named **BG_cat.tex** in your directory.
 +
 +===== How to use it in Python =====
 +The classes have not really been tested in Python. The following procedure seems to work, though.
 +Copy the file **libToolClasses.so** in your working directory. Start python and type:
 +  *''import GaudiPython''
 +  *''GaudiPython.loaddict('STLRflx')''
 +  *''import sys, ROOT''
 +  *''import libToolClasses'' It will complain about "dynamic module does not define init function".
 +  *''from ROOT import BGlatex, convPDGnumber'' 
 +  *''a = BGlatex()''
 +  *''a.makeTable()'' (or with arguments)
 +  *CTRL-D
 +This should have created a file named **BG_cat.tex** in your directory.
 +===== Disclaimer =====
 +Most of the above programming was done in a Trial-and-Error fashion and things have not been extensively tested. Feel free to add comments or report bugs.
