This manual is intended for people who have never used TeX before, as
well as for experienced TeX hackers. In other words, it's supposed to
be a panacea that satisfies everybody, at the risk of satisfying nobody.
Everything you need to know about TeX is explained
here somewhere, and so are a lot of things that most users don't care about.
If you are preparing a simple manuscript, you won't need to
learn much about TeX at all; on the other hand, some
things that go into the printing of technical books are inherently
difficult, and if you wish to achieve more complex effects you
will want to penetrate some of TeX's darker corners. In order
to make it possible for many types of users to read this manual
effectively, a special sign is used to designate material that is
for wizards only: When the symbol
$$vbox{hbox{dbend}vskip 11pt}$$
appears at the beginning of a paragraph, it warns of a ``^{dangerous bend}''
in the train of thought; don't read the paragraph unless you need to.
Brave and experienced drivers at the controls of TeX will gradually enter
more and more of these hazardous areas, but for most applications the
details won't matter.
