=head1 NAME
Pod::Html - module to convert pod files to HTML
=over 4
+=item backlink
+
+ --backlink="Back to Top"
+
+Adds "Back to Top" links in front of every HEAD1 heading (except for
+the first). By default, no backlink are being generated.
+
+=item css
+
+ --css=stylesheet
+
+Specify the URL of a cascading style sheet.
+
+=item flush
+
+ --flush
+
+Flushes the item and directory caches.
+
+=item header
+
+ --header
+ --noheader
+
+Creates header and footer blocks containing the text of the NAME
+section. By default, no headers are being generated.
+
=item help
--help
Sets the base URL for the HTML files. When cross-references are made,
the HTML root is prepended to the URL.
+=item index
+
+ --index
+ --noindex
+
+Generate an index at the top of the HTML file. This is the default
+behaviour.
+
=item infile
--infile=name
Specify the pod file to convert. Input is taken from STDIN if no
infile is specified.
-=item outfile
-
- --outfile=name
-
-Specify the HTML file to create. Output goes to STDOUT if no outfile
-is specified.
-
-=item podroot
-
- --podroot=name
-
-Specify the base directory for finding library pods.
-
-=item podpath
-
- --podpath=name:...:name
-
-Specify which subdirectories of the podroot contain pod files whose
-HTML converted forms can be linked-to in cross-references.
-
=item libpods
--libpods=name:...:name
=item netscape
--netscape
+ --nonetscape
-Use Netscape HTML directives when applicable.
-
-=item nonetscape
+Use Netscape HTML directives when applicable. By default, they will
+B<not> be used.
- --nonetscape
+=item outfile
-Do not use Netscape HTML directives (default).
+ --outfile=name
-=item index
+Specify the HTML file to create. Output goes to STDOUT if no outfile
+is specified.
- --index
+=item podpath
-Generate an index at the top of the HTML file (default behaviour).
+ --podpath=name:...:name
-=item noindex
+Specify which subdirectories of the podroot contain pod files whose
+HTML converted forms can be linked-to in cross-references.
- --noindex
+=item podroot
-Do not generate an index at the top of the HTML file.
+ --podroot=name
+Specify the base directory for finding library pods.
-=item recurse
+=item quiet
- --recurse
+ --quiet
+ --noquiet
-Recurse into subdirectories specified in podpath (default behaviour).
+Don't display I<mostly harmless> warning messages. These messages
+will be displayed by default. But this is not the same as C<verbose>
+mode.
-=item norecurse
+=item recurse
+ --recurse
--norecurse
-Do not recurse into subdirectories specified in podpath.
+Recurse into subdirectories specified in podpath (default behaviour).
=item title
Specify the title of the resulting HTML file.
-=item css
-
- --css=stylesheet
-
-Specify the URL of a cascading style sheet.
-
=item verbose
--verbose
+ --noverbose
-Display progress messages.
-
-=item quiet
-
- --quiet
-
-Don't display I<mostly harmless> warning messages.
+Display progress messages. By default, they won't be displayed.
