4.3 Free Text
Free text
 is any text that is not part of a macro definition or a directive. A scrap of
free text consists of a sequence of items drawn from the following list: non special
printable characters, insert eol special sequences, insert special character special
sequences, insert arbitrary character special sequence.
free_text      = ordinary_text
ordinary_text  = { ordinary_char | eol | text_special }+
1 Introduction
text_special   = "@+" | "@@" | "@^" char_spec
2 Interface
ordinary_char  = " ".."~"   special

5 Analyser
This@@ is a very@+ messy
6 Tangle
@^D(009)chunk of text indeed.
7 Weave
But FunnelWeb still views it as

a single chunk of text.

FunnelWeb never sees two text chunks next to each other in the input; they are

always merged into a single text token.

The free text in an input file does not affect the product files. However, by default,
it appears in the printed documentation exactly as it is given in the input file, except
that it is filled and justified into paragraphs.
Any printable character or particular sequence of characters may appear in the free
text of a document. FunnelWeb ensures that they will appear exactly as given in the
input file, even if they happen to be escape characters or commands in the target
typesetter. However, FunnelWeb also provides a special mode that allows this
censoring to be overridden.
