[Brahms-dev-l] PROOF with your own library

Hello.  Since a few people asked me about using own library with PROOF 
session, this is my (not so complete) answer.  At first, the instruction 
on ROOT page is none existing. If you do search on the web, these are 
the better instuctions found on the web.

http://people.web.psi.ch/feichtinger/doc/proof_examples.html
http://www-linux.gsi.de/~manteufe/docus/Introduction_version2.html

Here is a simple instructions.

A. Some simple instruction (may not be complete): (If you just want to 
load ready made library).
1.  You need to create directory MyLibrary (or something else)
2.  In there, you make other directory PROOF-INF
3.  In this directory, make SETUP.C file
    Here, you write a simple root macro to load your library.  for example,

Int_t SETUP()
{
    gSystem->Load("libBratModuleCent.so");
    // here you might also set incldue path and other.
    return 1;
}

4.  Then, from MyLibrary directory, you create par package by tar -czvf 
MyLibrary.par MyLibrary
5.  start root
6.  start proof  gROOT->Proof("proofserver","proof_config_file");
7.  gProof->UploadPackage("MyLibrary.par");  // this copy the files to 
all proof slaves.
8.  gProof->EnablePackage("MyLibrary");  // this seems to excute your 
SETUP.C
9.  The rest is the same as what you usually do for proof.  TDSet etc....

B.  If you have some library needed to compilied, you needs to the 
following additional steps.
1.  In MyLibrary directory, copy all sources to that directory.
2.  In MyLibrary directory, create Makefile for your library
3.  In PROOF-INF directory, make BUILD.sh, which says "make" (or 
whatever the instuction to run your make file.)
