Due to this statement, I've got the question.  What is the copyright 
status of MOPAC7.  Or more preciselly, where can I use its code?

As it is stated in the beginning of aababc.f:

C
C         Notice of Public Domain nature of this Program
C
C      'This computer program is a work of the United States
C       Government and as such is not subject to protection by
C       copyright (17 U.S.C. # 105.)  Any person who fraudulently
C       places a copyright notice or does any other act contrary
C       to the provisions of 17 U.S. Code 506(c) shall be subject
C       to the penalties provided therein.  This notice shall not
C       be altered or removed from this software and is to be on
C       all reproductions.'
C

Does this means I can use this code anywhere I want?  Can I sell it or
the code, derived for it?  Or, possibly, only use it for non-commercial
purposes?

Any hint will be helpfull.

Are they listed somewhere for public access?

Please, respond directly to me (akhavr@compchem.kiev.ua).  
If there will be requests, I will post the summary.

Thanks.

	*******************************************

A three day Workshop will be held in Tempe, AZ (Arizona State
University)  on February 19-21, 1997. The workshop goals are to
bring together researchers and practitioners of  Voronoi diagrams, Delaunay
triangulations, and multivariate splines from various scientific
fields including biology, chemistry, physics, medicine, together with
computational scientists and engineers in the areas of 
combinatorial geometry, computer-aided geometric design, 
computational algebraic geometry, computer graphics, data
visualization, image  processing and mesh generation.
The diversity of attendees should generate several
exciting cross-disciplinary results, and should
also help researchers in finding new collaborative
opportunities. This is the first attempt at bringing together such
a variety of researchers and thus constitutes  a unique
interdisciplinary effort. 

The Workshop shall be limited to 50 participants.
The Workshop structure will be to hold talks on the main topic areas.
The main emphasis is placed on the computational aspects of geometric 
problems that arise in the generation  and manipulation of Voronoi
diagrams, and its dual, and in spline formulations over these spatial 
subdivisions.Research contributions ranging from theoretical results
in algorithm design, sequential or parallel, to application research 
practices and experiences in the above-mentioned areas are welcome. 


Admissions to the workshop may be made both by potential speakers and
non-speaking attendees.  Potential speakers will be given a preference.  A
limited number of speakers will be selected from the submitted. 
Attendees are expected to be present for the entire Workshop and to
actively contribute.
Persons desiring to talk at the Workshop should submit a talk abstract (1
page) and a bio (1/2 page) electronically to Gerald Farin at the email
address (farin@asu.edu) and making the email subject
"Admission to Voronoi Workshop."  The talk abstract should focus on research
issues in one of the workshop sub-topics. Since the
Workshop will be limited to a maximum of 50 persons, we will select
attendees based on the applicability of the proposed talk and background in
the field.  Again, it is not necessary to offer to give a talk to attend the Workshop, but potential speakers will have priority for attending.
Workshop talks should focus on research at a high level, i.e.
current research) and future research
issues.  We estimate twenty-five minutes per selected talk.  

We expect to have NSF funds for this workshop to support junior
researchers. If you need such assistance, please indicate.
