 This package provides a C++ interface class to the VMD molfile
 plugins, http://www.ks.uiuc.edu/Research/vmd/plugins/molfile, and a
 set of LAMMPS classes that use this interface.
 
 Molfile plugins provide a consistent programming interface to read and
 write file formats commonly used in molecular simulations.  This
 package only provides the interface code, not the plugins; these can
 be taken as precompiled binaries directly from a VMD installation that
 matches the platform of your LAMMPS executable.  Using the plugin
 interface one can add support for additional file formats to LAMMPS
 simply by telling LAMMPS where to find a suitable plugin without
 having to recompile or change LAMMPS directly.  The plugins bundled
 with VMD are usually installed in a directory inside the VMD
 installation tree named "plugins/<VMDARCH>/molfile".
 
 To be able to dynamically load and execute the plugins from inside
 LAMMPS, you need to link with an appropriate system library, which
 is done using the settings in lib/molfile/Makefile.lammps.  See
 that file and the lib/molfile/README file for more details.
 
 NOTE: while the programming interface (API) to the molfile plugins is
 backward compatible (i.e. you can expect to be able to compile this
 package for plugins from newer VMD packages), the binary interface
 (ABI) is not.  So it is necessary to compile this package with the
 molfile plugin header files (vmdplugin.h and molfile_plugin.h) taken
 from the _same_ VMD installation that the (binary) plugin files are
 taken from.  These header files can be found inside the VMD
 installation tree under: "plugins/include".
 
 For convenience, this package includes a set of header files that is
-compatible with VMD 1.9 and 1.9.1 (the current version in June 2012)
-and should be compilable with VMD versions back to about version 1.8.4
+compatible with VMD 1.9.3 (the current version in April 2017)
