/test/compile-standalone.sh

#!/bin/bash

## This script allows to compile the program as standalone, taking ROOT and BOOST from CERN AFS
## It also takes python 2.6 from /usr/bin/python2.6 in case your default python is 2.4 like in SLC5
## It is meant only for DEBUGGING and TESTING, and it is NOT supported.
## 
## Usage:
##  - if necessary, fix the paths to BOOST, GCC, ROOT
##  - go under HiggsAnalysis/CombinedLimit, and
##     - if necessary, clean up a previous build with
##         ./test/compile-standalone.sh clean
##     - if necessary, compile the program
##         ./test/compile-standalone.sh make
##     - setup your environment 
##         eval $(./test/compile-standalone.sh env)
##  - now you can run the program
