Let us now praise free software

Setting up a free SGML editing and publishing system would not be possible without those programmers who release free software on the web. We should not take it for granted that we can obtain versatile, rock-solid, non-crashing software with full support through the Usenet or mailing lists, with the program sources and a license which entitles everybody to modify and improve it, at no cost. Many, many kudos to all those who make this possible.
