>TeX is *FREE*?!?!?
 
TeX is a document processing language written by Donald Knuth and is in the
public domain.  Also in the public domain is Knuth's source code for a
generic TeX to DVI processor and other supporting software.
 
However, any implementation of TeX or LaTeX for a particular machine may be
PD, shareware, or commercial software.  (eg. PCTeX and TeXtures are commercial,
but OZTeX is PD).
 
A similar situation exists for programming languages like Pascal. The language
itself is PD, but specific implementation like Turbo Pascal certainly are not.
