Generates ASCII tractors.
r------- _| / |_______\_ \\ | |o|----\\ |_____________\_--_\\ (O)_O_O_O_O_O_(O) \\
This program generates ASCII tractors using the universal tractor coefficient (TC). The intended audience is practical ASCII tractor theorists and lay people interested in abstract tractor theory.
Before using this program, ensure that you understand the fundamental theorem of ASCII tractor mechanics:
"ASCII Tractors must have at least four wheels." 
Note that this theorem applies to side-on views. No useful models of two-sided ASCII tractors have been found, nor is there even any concrete proof of their existence.
In keeping with this theorem, TRACTORGEN will politely inform the user if any attempt to make tractors with less than four wheels is made (by calling abort(2) and dumping core).
Please remember that information regarding the location of binaries for download is outlined in section 4.1.

Thu Dec 12 2002 Robin Elfrink has made the exploration of ASCII tractor mechanics accessible to yet another technical community with the creation of a tractorgen FreeBSD port. Well done Robin!
Tue Apr 30 2002 Robin Elfrink has created a web interface for TRACTORGEN, accessible at http://eddy.introweb.nl. He notes that "it has no problem creating a tractor with 99999 or more wheels, except that the browser will not render it correctly." Updated Wed May 8 2002 Further information from Mr. Elfrink suggests "the sparc with the webinterface is currently still recovering from a request for a tractor with 9999999 wheels last saturday by a (now former) friend of mine," so the availability of this web interface cannot be assured.
Tue Apr 30 2002 Robin Elfrink has made Debian GNU/Linux packages for several platforms including MIPS, Alpha and Sparc.
Wed Mar 13 2002 "As a service to the windows community", Doug Winter has made such a binary of TRACTORGEN.
Tue Sep 5 2000 Dave Fischer has made binaries for VAX and a OpenBSD (i386 and Sparc) available here.
Mon Apr 17 18:17:37 EST 2000 Horms has created RedHat packages for TRACTORGEN. These are available in the Download section. The Download section is after this line:
The current version is 0.31.7. No other version has ever existed. I can't think of any way to improve this software; perhaps it could make ice cream or something, that would be cool.
deb http://debian.a3.nl/debian a3 mainAlternatively, these files are available for download here.
tractorgen-0.31.7.tar.gz [HTTP] (37KB TAR Archive)
tractorgen-0.31.7-1.src.rpm [FTP] (40KB source RPM)
4.3 RPM .spec
This file is for people who want to build RPM packages of TRACTORGEN. These people are sick in the head. Thanks to Horms for making this possible.
4.4 Debian packaging files
If you would like to build or rebuild Debian packages for your platform, the required files are available here. Thanks to Robin Elfrink for this packaging.
4.5 FreeBSD port directory
This is an archive of the port directory from which the binary can be built.
You must read the ChangeLog before purchasing this product.
Verge Networks has kindly supplied a mailing list to cater for the ASCII tractor community. If there were to be any new releases of TRACTORGEN, they would be announced here. Failing that, this list will be used for noteworthy news items related to the general implementation of ASCII tractor mechanics, and issues related to performance tuning and benchmarking of the TRACTORGEN software.
To subscribe to this list, please browse to the mailing list administration interface. Unfortunately the following link to the aforementioned interface contains a typographical error: tractor-enthusiasts. Thankyou to the alert readers (many of you!) who have written in to notify the author of this error. As always, your kind technical advice is very much appreciated.
