Dear All,

I would like to announce a first release of ruby-sphere: a set of
libraries and user interfaces to calculate apparent positions of stars
with a moderate accuracy.

Please have a look at the project homepage
  http://ruby-sphere.sourceforge.net/
and download the package from
  http://prdownloads.sourceforge.net/ruby-sphere/ruby-sphere-0.1.0.tar.gz?download

The goal of ruby-sphere is to to provide an easy way to plan
astronomical observations. The release 0.1.0 contains a set of libraries
to plot visibility maps and a sample script to be edited for your own
application. Ruby version 1.8.x is recommended. Gnuplot is required to
plot visibility maps.

Best regards,
Daigo
