+
+Sets the base URL for the HTML files. When cross-references are made,
+the HTML root is prepended to the URL.
+
+=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
+
+List of page names (eg, "perlfunc") which contain linkable C<=item>s.
+
+=item netscape
+
+ --netscape

+
+ --nonetscape
+
+Do not use Netscape HTML directives (default).

+=item noindex
+
+ --noindex
+
+Do not generate an index at the top of the HTML file.
+
+
+=item recurse
+
+ --recurse
+
+Recurse into subdirectories specified in podpath (default behaviour).
+
+=item norecurse
+
+ --norecurse
+
+Do not recurse into subdirectories specified in podpath.
