Availability

The mathrec source code is freely redistributable. The author maintains binary distributions for Caldera OpenLinux 3.1, OpenServer, UnixWare 7 and Open UNIX 8. These distributions and the source code are available via:

Description

The mathrec package consists of several X11 clients :

coral	endo	gasket	hop	julia	lds	lyap
madness	mandel	splines	spore	stars	xtopo	xwator

Build

To build the mathrec binaries, use the Imakefile. To build with the Imakefile, first type "xmkmf -a" or "imake -DUseInstalled -I/usr/lib/X11/config" if your system doesn't have xmkmf. Then just type "make" and the mathrec binaries will be built.

Install

To install mathrec, you can simply run "make install; make install.man". Since mathrec is built with imake, it honors the DESTDIR setting. So, if you want to install the mathrec package in a "packaging ground", you can set the DESTDIR environment variable to the location below which the files will be installed.

Known Limitations

These programs were originally written for 8-bit PseudoColor X11 displays. I have modified them so that they work on a TrueColor visual but many of the features are not present without a PseudoColor display. For instance, the installation of a private colormap and the spinning of the color map are features available only on a PseudoColor display visual.

Productivity

These programs and others like them are probably responsible for more CPU cycles than any other single application.

Safety

I have used these for years without harm.

Work Planned
