.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 HTML 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 URL of a cascading style sheet.  Also disables all HTML/CSS
\&\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 URL for the HTML files.  When cross-references are made,
the HTML root is prepended to the URL.
.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 HTML 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 STDIN if no
infile is specified.
.IP outfile 4
.IX Item "outfile"
.Vb 1
\&    \-\-outfile=name
.Ve
.Sp
Specify the HTML file to create.  Output goes to STDOUT if no outfile
is specified.
.IP poderrors 4
.IX Item "poderrors"
.Vb 2
\&    \-\-poderrors
\&    \-\-nopoderrors
.Ve
.Sp
Include a "POD ERRORS" section in the outfile if there were any POD 
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
HTML 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 HTML file.
.IP verbose 4
.IX Item "verbose"
.Vb 2
\&    \-\-verbose
\&    \-\-noverbose
.Ve
.Sp
Display progress messages.  By default, they won't be displayed.
.SS "Formerly Exported Auxiliary Functions"
.IX Subsection "Formerly Exported Auxiliary Functions"
Prior to perl\-5.36, the following three functions were exported by
\&\fIPod::Html\fR, either by default or on request:
.IP \(bu 4
\&\f(CWhtmlify()\fR (by default)
.IP \(bu 4
\&\f(CWanchorify()\fR (upon request)
.IP \(bu 4
\&\f(CWrelativize_url()\fR (upon request)
.PP
The definition and documentation of these functions have been moved to
\&\fIPod::Html::Util\fR, viewable via \f(CW\*(C`perldoc Pod::Html::Util\*(C'\fR.
.PP
Beginning with perl\-5.38 these functions must be explicitly imported from
\&\fIPod::Html::Util\fR.  Please modify your code as needed.
