.SH "NAME"
Pod::Html \- module to convert pod files to HTML
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 2
\&    use Pod::Html;
\&    pod2html([options]);
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Converts files from pod format (see perlpod) to \s-1HTML\s0 format.  It
can automatically generate indexes and cross-references, and it keeps
a cache of things it knows how to cross-reference.
.SH "FUNCTIONS"
.IX Header "FUNCTIONS"
.SS "pod2html"
.IX Subsection "pod2html"
.Vb 7
\&    pod2html("pod2html",
\&             "\-\-podpath=lib:ext:pod:vms",
\&             "\-\-podroot=/usr/src/perl",
\&             "\-\-htmlroot=/perl/nmanual",
\&             "\-\-recurse",
\&             "\-\-infile=foo.pod",
\&             "\-\-outfile=/perl/nmanual/foo.html");
.Ve
.PP
pod2html takes the following arguments:
.IP "backlink" 4
.IX Item "backlink"
.Vb 1
\&    \-\-backlink
.Ve
.Sp
Turns every \f(CW\*(C`head1\*(C'\fR heading into a link back to the top of the page.
By default, no backlinks are generated.
.IP "cachedir" 4
.IX Item "cachedir"
.Vb 1
\&    \-\-cachedir=name
.Ve
.Sp
Creates the directory cache in the given directory.
.IP "css" 4
.IX Item "css"
.Vb 1
\&    \-\-css=stylesheet
.Ve
.Sp
Specify the \s-1URL\s0 of a cascading style sheet.  Also disables all \s-1HTML/CSS\s0
\&\f(CW\*(C`style\*(C'\fR attributes that are output by default (to avoid conflicts).
.IP "flush" 4
.IX Item "flush"
.Vb 1
\&    \-\-flush
.Ve
.Sp
Flushes the directory cache.
.IP "header" 4
.IX Item "header"
.Vb 2
\&    \-\-header
\&    \-\-noheader
.Ve
.Sp
Creates header and footer blocks containing the text of the \f(CW\*(C`NAME\*(C'\fR
section.  By default, no headers are generated.
.IP "help" 4
.IX Item "help"
.Vb 1
\&    \-\-help
.Ve
.Sp
Displays the usage message.
.IP "htmldir" 4
.IX Item "htmldir"
.Vb 1
\&    \-\-htmldir=name
.Ve
.Sp
Sets the directory to which all cross references in the resulting
html file will be relative. Not passing this causes all links to be
absolute since this is the value that tells Pod::Html the root of the 
documentation tree.
.Sp
Do not use this and \-\-htmlroot in the same call to pod2html; they are
mutually exclusive.
.IP "htmlroot" 4
.IX Item "htmlroot"
.Vb 1
\&    \-\-htmlroot=name
.Ve
.Sp
Sets the base \s-1URL\s0 for the \s-1HTML\s0 files.  When cross-references are made,
the \s-1HTML\s0 root is prepended to the \s-1URL.\s0
.Sp
Do not use this if relative links are desired: use \-\-htmldir instead.
.Sp
Do not pass both this and \-\-htmldir to pod2html; they are mutually
exclusive.
.IP "index" 4
.IX Item "index"
.Vb 2
\&    \-\-index
\&    \-\-noindex
.Ve
.Sp
Generate an index at the top of the \s-1HTML\s0 file.  This is the default
behaviour.
.IP "infile" 4
.IX Item "infile"
.Vb 1
\&    \-\-infile=name
.Ve
.Sp
Specify the pod file to convert.  Input is taken from \s-1STDIN\s0 if no
infile is specified.
.IP "outfile" 4
.IX Item "outfile"
.Vb 1
\&    \-\-outfile=name
.Ve
.Sp
Specify the \s-1HTML\s0 file to create.  Output goes to \s-1STDOUT\s0 if no outfile
is specified.
.IP "poderrors" 4
.IX Item "poderrors"
.Vb 2
\&    \-\-poderrors
\&    \-\-nopoderrors
.Ve
.Sp
Include a \*(L"\s-1POD ERRORS\*(R"\s0 section in the outfile if there were any \s-1POD\s0 
errors in the infile. This section is included by default.
.IP "podpath" 4
.IX Item "podpath"
.Vb 1
\&    \-\-podpath=name:...:name
.Ve
.Sp
Specify which subdirectories of the podroot contain pod files whose
\&\s-1HTML\s0 converted forms can be linked to in cross references.
.IP "podroot" 4
.IX Item "podroot"
.Vb 1
\&    \-\-podroot=name
.Ve
.Sp
Specify the base directory for finding library pods. Default is the
current working directory.
.IP "quiet" 4
.IX Item "quiet"
.Vb 2
\&    \-\-quiet
\&    \-\-noquiet
.Ve
.Sp
Don't display \fImostly harmless\fR warning messages.  These messages
will be displayed by default.  But this is not the same as \f(CW\*(C`verbose\*(C'\fR
mode.
.IP "recurse" 4
.IX Item "recurse"
.Vb 2
\&    \-\-recurse
\&    \-\-norecurse
.Ve
.Sp
Recurse into subdirectories specified in podpath (default behaviour).
.IP "title" 4
.IX Item "title"
.Vb 1
\&    \-\-title=title
.Ve
.Sp
Specify the title of the resulting \s-1HTML\s0 file.
.IP "verbose" 4
.IX Item "verbose"
.Vb 2
\&    \-\-verbose
\&    \-\-noverbose
.Ve
.Sp
Display progress messages.  By default, they won't be displayed.
.SS "htmlify"
.IX Subsection "htmlify"
.Vb 1
\&    htmlify($heading);
.Ve
.PP
Converts a pod section specification to a suitable section specification
for \s-1HTML.\s0 Note that we keep spaces and special characters except
\&\f(CW\*(C`", ?\*(C'\fR (Netscape problem) and the hyphen (writer's problem...).
.SS "anchorify"
.IX Subsection "anchorify"
.Vb 1
\&    anchorify(@heading);
.Ve
.PP
Similar to \f(CW\*(C`htmlify()\*(C'\fR, but turns non-alphanumerics into underscores.  Note
that \f(CW\*(C`anchorify()\*(C'\fR is not exported by default.
.SH "ENVIRONMENT"
.IX Header "ENVIRONMENT"
Uses \f(CW$Config{pod2html}\fR to setup default options.
.SH "AUTHOR"
.IX Header "AUTHOR"
Marc Green, <marcgreen@cpan.org>.
