NAME

       roffit - convert nroff to HTML

SYNOPSIS

       roffit [options] < inputfile > outputfile

DESCRIPTION

       roffit  converts  the  inputfile to outputfile. The inputfile must be an nroff formatted man page, and the outputfile will be an HTML docu-
       ment.

OPTIONS

       --bare The output HTML will not include any HTML, HEAD or BODY tags. Also not that when this is selected, there will be no inlined CSS  but
	      you will have to define the necessary classes yourself.

       --version
	      Display version number and exit

       --mandir=<dir>
	      Set  a  directory in which roffit will check for other man pages (in nroff [name].[num] format) that this one refers to. If found, a
	      <a href> link will be made to that page with a html extension instead of the number. The file name in the  generated  link  will	be
	      prefixed by the dir given with --hrefdir.

	      This  works  for references specified as manpage(3) (within the emhpasis foformatting) and in a plain .BR section (often used in the
	      SEE ALSO section).

       --hrefdir=<dir>
	      Specify a directory to prefix generated href links created with the --mandir option. This defaults to ".".

CSS CLASSES

       h2.nroffsh
	      The nroff ".SH" section. These are normally the "headlines" before each sub section within the man page.

       p.nroffip
	      The nroff ".IP" section. These are normally the bullet kind used to list each option out of several in a list. Usually followed by a
	      p.level0 containining the descriptive text.

       p.level0
	      Normal text at the first level. Normally not indented.

       p.level1
	      Text at next logical indent level. Normally indented one level right.

       p.level2
	      Text at the second logical indent level. Normally indented two levels right.

       span.bold
	      Text marked to be bold.

       span.manpage
	      Text marked as a reference to another man page.

       span.emphasis
	      Text marked to be emphasized.

       p.roffit
	      Used for the advertising final paragraph.
