If the necessary tools (LYX, LATEX, LATEX2HTML) are installed it is as easy as changing into the doc directory and typing ''make'' there. You're invited to make changes and additions to this manual (sdcc/doc/sdccman.lyx). Using LYX www.lyx.org as editor this is straightforward. If you want to avoid installing the tools you will have some success with a bootable Knoppix CD http://www.knoppix.net. Prebuilt documentation in html and pdf format is available from http://sdcc.sourceforge.net/snap.php.
