###############################################################################

PFTool (Parallel File Tool) can stat, copy, and compare files in parallel. 
It's optimized for an HPC workload and uses MPI for message passing.

***************************************************************************
Dependencies
***************************************************************************

autoconf
automake
m4
libtool
mpi

***************************************************************************
Installing PFTool
***************************************************************************
From the top-level directory

./autogen

#To configure the base version:
./configure

#To configure the threaded version:
#./configure --enable-threads

#Other options:
#./configure --help

./make clean
./make all
./make install

Note that pftool.cfg is created and installed into {install_prefix}/etc
during the "make install". Setting in this file should be reviewed and 
modified based on the configuration of the cluster the software is
running on. 

***************************************************************************
PFTool RPM
***************************************************************************
To build an RPM, from the top-level directory:

cd package
make rpm

Rpmbuild is used by this make file to generate the RPM. It is assumed that
the directory/tree $HOME/rpmbuild exists and has the subdirectories SOURCES,
BUILD, and RPMS. The resulting RPM is written to $HOME/rpmbuild/RPMS.

***************************************************************************
Configuration
***************************************************************************
{install_prefix}/etc/pftool.cfg is read by the pftool scripts pfls, pfcm, pfcp

example config files located in ./etc/. 

***************************************************************************
Versioning
***************************************************************************
In order to change the version number for this project, modify the following
line in ./configure.ac:

AC_INIT([pftool], [2.0.5], [[email protected]])

Then rerun

./configure

Note that the maintainer information can be changed as well.

***************************************************************************
Using PFtool
***************************************************************************
PFTool can be invoked directly, but the preferred method is through helper
scripts located in {install_prefix}/scripts/
