About this Document

This document has been made on a Linux computer (SuSE 7.3):

• It is created using LYX-1.1.6 and exported as TEX. LYX is a graphical frontend to L^ATEX. L^ATEX is a professional book setting program. Compared to ordinary text processing programs L^ATEX has no bugs--the last bug has been found and fixed some years ago (and the fix has been payed). The schematics have been imported using the epsf-package (\usepackage{epsf}).
• TEX is processed by L^ATEX-2e into dvi, which is converted into Postscript by dvips-5.86, which is again converted into PDF using ps2pdf (GNU Ghostscript 6.51). dvips is the Postscript printer driver of L^ATEX. Ghostscript is a printer driver for printers which cannot process plain Postscript. PDF (Portable Document Format) is a proprietary file format of Adobe (TM).
• TEX is converted into HTML using latex2html-99.2beta8. All none automatic created links have been created using the html-packages (\usepackage{html}). latex2html is a Perl script which reads a TEX file and creates HTML pages. Perl is a powerful system independent interpreter language and replaces the system dependent shell script languages.
• The schematics are converted from Postscript into PDF using ps2pdf (see above).
• The whole conversion and the installation onto my homepage is automatically done by GNU make-3.79.1 using a makefile. make is a tool for the automatic build of projects of any kind which consist of several dependent files and which are build using command line tools.
• All source files are controlled by CVS-1.11. CVS (Concurrent Versions System) is a source code management program.
• All used programs are free software which fall either under the GPL (GNU Public License) or a similar license for none commercial purposes. The sources are open and may be compiled on most Unix systems.
