.
.Sh DESCIPTION
.Pp
.Nm
is a utility that generates HTML from
.Xr troff 1
source code.
.Pp
While
.Nm
is named like a troff macro package and uses troff syntax, it is a standalone utility that does not use troff itself.
As such, it supports only a subset of the standard troff requests.
.
.Sh USAGE
.Pp
This section describes the various types of requests supported by
.Nm .
On the left side are the name and arity of each request, separated by a slash.
On the right side is the HTML expansion of each request.
.Pp
In the HTML expansion of all element requests, a backslash and a dollar sign followed by a number (e.g. \\$1) signify a parameter expansion.
.Pp
In block element requests, a percent sign (%) signifies the lines following the request until the next block element request.
.Pp
Finally, in contiguous element requests, whatever text is on the outside of the area delimited by braces ({...}) is removed when two of the same contiguous element requests are placed next to one another.
