# script: traf_tools_setup
#
# Helper script that downloads and installs dependent tools required by 
# Apache Trafodion to build from a source distribution
#
# Tools installed:
#
# MPICH: Implementation of the Message Passing Interface (MPI) standard.  For use 
#   in Trafodion, MPICH must be built to force sockets to be used in both 
#   internode and intranode message passing. 
# Bison: General-purpose parser generator.
# Udis86: Minimalistic disassembler library (libudis86) for the x86 class of 
#   instruction set architectures.
# LLVM: Collection of modular and reusable compiler and toolchain technologies.
# ICU: C/C++ and Java libraries providing Unicode and Globalization support for 
#   software applications.
# Zookeeper: Coordination service for distributed applications.  It exposes 
#   common services such as naming, configuration management, synchronization, 
#   and group services.
# Thrift: Communications and data serialization tool
# Maven: Build tool that is only installed if compatible version does not exist
# log4cxx: standard logging framework for C++
# hadoop: shared libraries for libhadoop, libhdfs, and hdfs header file
#
# Script can be modified to meet the needs of your environment
# May need root or SUDO access to install tools in desired location
