.TH EGON 1 LOCAL .SH NAME egon \- Egon Animator .SH SYNOPSIS .B egon [X-options] [siod-options] [filename...] .SH DESCRIPTION .I Egon is an X-based animation package for Unix. It uses Scheme both for expressions and as a macro language, which makes it easy to create new functions. The Scheme interpreter is .I SIOD written by George Carrette. .SH COMMAND LINE OPTIONS .TP .BI X-options See on-line documentation. .TP .BI SIOD-options See on-line documentation. .SH ENVIRONMENT .TP .BI HOME is the name of the user's home directory. .TP .BI PRINTER is the name of the default printer destination. .TP .BI SIAGHELP is the name of Egon's online help browser, normally Netscape although any HTML browser can be used. .TP .BI SIAGHOME is the name of Egon's "home" directory, normally /usr/local/lib/siag. .TP .BI SIAGDOCS is the name of the directory where the online documentation is installed. .SH FILES .TP .BI $SIAGHOME/egon/egon.scm is automatically read on startup and contains a runtime library including many of the functions that are necessary for normal operation. PW will not work properly without this file. .TP .BI $SIAGHOME/egon/menu.scm is also read on startup and contains the code to set up menus. Failure to load this file will result in all the menus being empty. .TP .BI $HOME/.siag/egon.scm contains optional Scheme code which should be loaded after siag.scm but before any documents. .PD .SH SEE ALSO On-line documentation, which contains more complete information about the invocation and usage of Egon. .SH DIAGNOSTICS Most error messages come from SIOD and are printed on the bottom line. See SIOD source and documentation for interpretation. .SH LIMITATIONS Egon can read and write several file formats (see on-line documentation for details). .SH BUGS Handles out of memory conditions ungracefully. And more. .SH VERSION Current version (21 March 2000) is Egon 3.3.0 by Ulric Eriksson, ulric\@siag.nu.

There is no reason to re-implement stuff that is already freely available. For copyright information and installation instructions, see the various packages. The sources are hacked by Yours Truly to give the programs a uniform look. If you don't approve of that and/or already have the programs installed, there is no need to install my versions. These are not the original versions. If my modifications break anything, complain to me about it, not the original authors. If the original versions work and mine don't, then don't use mine. .TP .BI SIOD The embedded Scheme interpreter is an extremely small interpreter called Siod, which can be used stand-alone or easily integrated into a program as an extension language.
