    <Location /perldoc>
        SetHandler  perl-script
        PerlHandler Apache2::Pod::HTML
        PerlSetVar  STYLESHEET auto
    </Location>

Specifying 'auto' for the stylesheet will cause the built-in CSS
stylesheet to be used.  If you prefer, you can replace the word 'auto'
with the URL of your own custom stylesheet file.

=head2 INDEX

When INDEX is true, a table of contents is added at the top of the
HTML document.

    <Files *.pod>
        SetHandler perl-script
        PerlHandler Apache2::Pod::HTML
        PerlSetVar INDEX 1
    </Files>

By default, this is off.

=head2 GZIP

When GZIP is true, the whole HTTP body is compressed.  The user's browser must 
accept gzip, and L<Compress::Zlib> must be available.  Otherwise, GZIP is ignored.

    <Files *.pod>
        SetHandler perl-script
        PerlHandler Apache2::Pod::HTML
        PerlSetVar GZIP 1
    </Files>

By default, this is off.

=head2 LINKBASE

Specifying an optional C<LINKBASE> variable changes the external
HTTP links to use a URL prefix of your specification instead of using
L<Pod::Simple::HTML>'s default.  Using the magic word C<LOCAL> will make
links local instead of external.
