// Description: 
// Chain for StPeCMaker based on doEvents.C. Runs StEventMaker and StPeCMaker.
//
// Environment:
// Software developed for the STAR Detector at Brookhaven National Laboratory
//
// Ways to run:
// If you specify a path, all DST files below that path will be
// found, and 'nevents' events from each will be analyzed.
// The type of DST files searched for is taken from the 'file' parameter.
// If 'file ends in '.xdf', XDF DSTs are searched for.
// If 'file ends in '.dst.root', ROOT DSTs are searched for.
//
// If path begins with '-', 'file' will be taken to be a single file
// to be processed.
//
// example invocation:
// .x runPeCMaker.C(10,"-","some_directory/some_dst_file.xdf")
//
// example ROOT file invocation:
// .x runPeCMaker.C(10,"-","some_directory/some_dst_file.root")
//
// example multi-ROOT file invocation:
// .x runPeCMaker.C(9999,"some_directory","*.dst.root")

// Revision 1.10  2010/03/16 16:23:09  fisyak
// StTpcDb requires StDetectorDbMaker
//
// Revision 1.9  2006/08/15 21:42:49  jeromel
// Fix rhic -> rhic.bnl.gov
//
// Revision 1.8  2005/08/31 15:03:09  fisyak
// Add dependence StMagF vs StarMagField
//
// Revision 1.7  2001/09/21 02:21:57  jeromel
// StTpcDb needed by StEventMaker.
//
// Revision 1.6  2000/05/09 19:38:35  kathy
// update to use standard default input files and only process few events by default - to make it easy to run in automatic macro testing script
//
// Revision 1.5  2000/04/18 20:20:33  nystrand
// StFile --> StFileI + updated chain return codes
//
// Revision 1.4  2000/04/13 21:46:35  kathy
// remove loading of libtpc_Tables since l3Track table is now dst_track type from global
//
// Revision 1.3  2000/04/12 15:06:53  kathy
// changed all macros that read DSTs to load Tables from libraries: gen,sim,global,dst instead of ALL Tables (previously loaded St_Tables); currently, if you are using DEV to read a DST in NEW,PRO, you must comment out the loading of libtpc_Tables because of a mismatch with tpt_track table
//
// Revision 1.2  2000/04/03 20:47:32  nystrand
// Bug fix
//
// Revision 1.1  2000/03/28 23:52:24  nystrand
// First version
//
// Revision 1.0  2000/03/27 18:20:20  ullrich
// First version.
