TROFF2HTML(1) TROFF2HTML(1)
NAME
troff2html - convert troff output into HTML
SYNOPSIS
troff2html [ -t title ] [ file ... ]
DESCRIPTION
Troff2html reads the troff(1) output in the named files,
default standard input, and converts them into HTML.
Troff2html does a tolerable job with straight troff output,
but it is helped by annotations, described below. Its main
use is for man2html (see httpd(8)), which converts man(1)
pages into HTML and depends on a specially annotated set of
man(6) macros, invoked by troff -manhtml.
Troff output lines beginning
x X html ...
which are introduced by placing \X'html ...' in the input,
cause the rest of the line to be interpolated into the HTML
produced. Several such lines are recognized specially by
troff2html. The most important are the pair
x X html manref start cp 1
x X html manref end cp 1
which are used to create HTML hyperlinks around text of the
form cp(1) pointing to /magic/man2html/1/cp.
Troff2html is new and experimental; in time, it may improve
and subsume ms2html(1). On the one hand, because it uses the
input, ms2html can handle pic(1), eqn(1), etc., which
troff2html does not handle at all; on the other hand,
ms2html understands only ms(6) documents and is easily con-
fused by complex troff constructions. Troff2html has the
reverse properties: it does not handle the preprocessors but
its output is reliable and (modulo helper annotations) is
independent of macro package.

BUGS
Troff and HTML have different models, and they don't mesh
well in all cases. Troff's indented paragraphs are not well
