What Gri is =========== Gri is a language for scientific graphics applications. By 'language' I mean that it is a command-driven application, as opposed to a click/point application. It is analogous to latex or tex, and shares the property that extensive power is the reward for tolerating a learning curve. Gri output is in PostScript, suitable for incorporation in documents prepared by various text processors. Gri can make x-y graphs, contour-graphs, and image graphs. In addition to high-level capabilities, it has enough low-level capabilities to allow users to achieve a high degree of customization. Control is extended to all aspects of drawing, including line widths, colors, and fonts. Text includes a subset of the tex language for letters and mathematical symbols in labels. Compiling and Installing Gri ============================ The normal case is to have received the Gri source as a so-called "tarball". If that is how you got Gri, then you should type ./configure make make install at the shell to create and install Gri. If there is a problem in these steps, trying typing aclocal autoconf automake --add-missing first to create some configuration files, and then you type ./configure make make install as usual.
