 This directory contains Python code which wraps LAMMPS as a library
 and allows the LAMMPS library interface to be invoked from Python,
 either from a script or interactively.
 
 Details on the Python interface to LAMMPS and how to build LAMMPS as a
 shared library, for use with Python, are given in
 doc/Section_python.html and in doc/Section_start.html#start_5.
 
 Basically you need to follow these steps in the src directory:
 
 % make makeshlib                # creates Makefile.shlib
-% make -f Makefile.shlib g++    # or whatever machine target you wish
+% make -f Makefile.shlib g++    # build for whatever machine target you wish
 % make install-python           # may need to do this via sudo
 
 You can replace the last step with running the python/install.py
 script directly to give you more control over where two relevant files
 are installed, or by setting environment variables in your shell
 script.  See doc/Section_python.html for details.
 
 You can then launch Python and instantiate an instance of LAMMPS:
 
 % python
 >>> from lammps import lammps
 >>> lmp = lammps()
 
 If that gives no errors, you have succesfully wrapped LAMMPS with
 Python.  See doc/Section_python.html#py_5 for tests you can then use
 to run LAMMPS both in serial or parallel thru Python.
 
 -------------------------------------------------------------------
 
 Once you have successfully wrapped LAMMPS, you can run the Python
 scripts in the examples sub-directory:
 
 trivial.py          read/run a LAMMPS input script thru Python
 demo.py	  	    invoke various LAMMPS library interface routines
 simple.py	    mimic operation of couple/simple/simple.cpp in Python
 gui.py		    GUI go/stop/temperature-slider to control LAMMPS
 plot.py		    real-time temeperature plot with GnuPlot via Pizza.py
 viz_tool.py	    real-time viz via some viz package
 vizplotgui_tool.py  combination of viz.py and plot.py and gui.py
 
 For the viz_tool.py and vizplotgui_tool.py commands, replace "tool"
 with "gl" or "atomeye" or "pymol", depending on what visualization
 package you have installed.  We hope to add a VMD option soon.
 
 Note that for GL, you need to be able to run the Pizza.py GL tool,
 which is included in the pizza sub-directory.  See the Pizza.py doc
 pages for more info:
 
 http://www.sandia.gov/~sjplimp/pizza.html
 
 Note that for AtomEye, you need version 3, and their is a line in the
 scripts that specifies the path and name of the executable.  See
 the AtomEye WWW pages for more details:
 
 http://mt.seas.upenn.edu/Archive/Graphics/A
 http://mt.seas.upenn.edu/Archive/Graphics/A3/A3.html
 
 The latter link is to AtomEye 3 which has the scriping
 capability needed by these Python scripts.
 
 Note that for PyMol, you need to have built and installed the
 open-source version of PyMol in your Python, so that you can import it
 from a Python script.  See the PyMol WWW pages for more details:
 
 http://www.pymol.org
 http://sourceforge.net/scm/?type=svn&group_id=4546
 
 The latter link is to the open-source version.
 
 -------------------------------------------------------------------
 
 You can run a particular script in either of the following ways:
 
 % trivial.py in.trivial
 % python -i trivial.py in.trivial
 
 The former assumes that you have changed the first line of the script
 to point to the Python installed on your box.
 
 Run the Python scripts with the following LAMMPS input scripts and
 arguments:
 
 trivial.py in.trivial
 demo.py
 simple.py in.simple
 gui.py in.gui 100
 plot.py in.plot 10 1000 thermo_temp
 viz_tool.py in.viz 100 5000
 vizplotgui_tool.py in.viz 100 thermo_temp
 
 You can un-comment the Pypar calls if you want to run these in
 parallel.
 
 Each script has more documentation in the file that explains how to
 use it and what it is doing.
