performs a similar service, but accepts as input text formatted with
HTML tags.
It accepts
.IR fmt 's
.B -l
and
.B -w
flags and also:
.TP

suppresses the contents of form fields and anchors (URLs and image files); this flag
causes it to print them, in square brackets.
.TP
.BI -c " charset
change the default character set from iso-8859-1 to
.IR charset .
This is the character set assumed if there isn't one
specified by the html itself in a <meta> directive.
.TP
.BI -u " url
Use
.I url
as the base URL for the document when displaying anchors; sets
.BI -a .

.SH BUGS
.I Htmlfmt
makes no attempt to render the two-dimensional geometry of tables;
it just treats the table entries as plain, to-be-formatted text.
