  We present a WWW-version of the {\it Scenario Machine} - a computer code
designed to calculate the evolution of close binary stellar systems. The
Internet users can directly access to the code and calculate binary
evolutionary tracks with parameters at the user's will. The program is running
on the {\it Pentium} server of the Division of the Relativistic Astrophysics of
the Sternberg Astronimical Institute (http://xray.sai.msu.su/ ). The results
are presented both in the form of tables and graphic diagrams. The work is
always in progress. More possibilities for Internet users are intended to
become available in the near future.
