Overview. `Gre ' (rhymes with `flee') is an extensible
plotting language designed by a scientist, for scientists. It can draw
x-y plots, contour plots, and image plots.
Manual. The `gre ' manual is on the web at
`http://www.phys.ocean.dal.ca/~kelley/gre'
If `gre ' is on your machine, the manual is also at
`file:/opt/gre/doc/html/gre1.html'.
The local copy is preferable because it refers to the version you are
using, but it's worth checking the web version once in a while to see
the new features.
History. `Gre ' is the descendant of the
`Gri '
language. There are two phases of `gre ' development: (1) creation of
a working parser with perl-like capabilities and (2) emulation of all
relevant Gri commands. Phase (1) is nearly complete. Phase (2) is
about 2/3 percent complete, measured by the fraction of Gri commands
that work in `gre '. The history chapter (see History) describes
the evolution of `gre '.
Today, `gre ' is in daily use by the author and a handful of beta
testers. Any experienced Gri user should be able to work with `gre '
quite easily, especially if they have some knowledge of the Perl
programming language.
Availability. `Gre ' is available for download at
ftp://ftp.phys.ocean.dal.ca/users/kelley/gre
The source is in a file called `gre-N.N.N.tgz' (a tar/gzip file).
Here, `N.N.N ' stands for the version number,
e.g. `gre-0.1.26.tgz'. Compilation is simple; just type
`./configure ' (answering any questions it asks) and then type
`make gre '. Linux users using the RedHat or Debian distributions
need not bother with compilation since pre-compiles packages
(`gre-N.N.N-1.i386.rpm' and `gri-N.N.N.deb') are provided.
