     README FOR USPP 7.3.5 PSEUDOPOTENTIAL GENERATION PROGRAM
     --------------------------------------------------------

This distribution contains version 7.3.5 of the "ultrasoft
pseudopotential" (USPP) generation code from the group of
D. Vanderbilt, Rutgers University.

This code is freely distributed.  You may use it for your own
research purposes, or pass it on to others for similar use.
However, note the following restrictions:

1. The code is not guaranteed to be bug-free.

2. The quality of the pseudopotentials generated by the provided input
   files is not guaranteed.

3. No active support is provided for this package.

4. The code may not be used for profit-making purposes or
   included in any commercial code except by express arrangement.

Version uspp-7.3.3 should be functionally identical to the previous
distribution known as a7.3.2.  All the significant modifications
are in the "packaging," i.e., the directory structure, the
Makefiles, the sample files, etc.  Two important modifications are
that:

-- The GNU GPL License is now explicitly included as a header
   of each source file.  See Source/LICENSE.

-- The Work subdirectory contains a library of input files that
   can be used to generate a library of pseudopotentials that
   will hopefully grow to cover many atoms of the periodic table.

Version uspp-7.3.4 and subsequent versions include minor compiler
compatibility improvements and bug fixes as detailed in the
Source/README file.

See the file AA-QUICK-START to find out how to compile and run
the program and generate the library of pseudopotentials.

Users who wish to experiment with generating their own
pseudopotentials should start by consulting the file Doc/TUTORIAL.
This is the closest thing there is to a "User Manual," but it is
not as complete as I would like.  So beware that this process may
not be entirely painless.

Users are strongly encouraged to donate their input files to expand
the library of available potentials.  See AA-SUBMISSIONS for more
information about how to do this.  Note that the version number
(currently 7.3.3) will NOT change just because of additions to the
library of input files.  Check the LAST-MODIFIED date in the Work/
directory to see if you have the latest version of the library.

See Source/README for a summary of improvements that were made to
the source codes from one release to the next.  More information
about the release history can also be found in the comments at the
beginning of the main program runatom.f.

Please direct comments or suggestions for improvement to David
Vanderbilt at dhv@physics.rutgers.edu.
