=head1 SYNOPSIS
|
||
|
||
B<pdfman> I<manentry>
|
||
|
||
|
||
=head1 DESCRIPTION
|
||
|
||
B<pdfman> uses B<man -t> to generate a PDF-version of the man page. It
|
||
is then displayed using $PDFVIEWER.
|
||
|
||
If $PDFVIEWER is unset, it tries B<okular>, B<evince>, and B<gv>.
|
||
|
||
If a viewer of the page is already running, a new viewer will not be
|
||
started.
|
||
|
||
=head1 EXAMPLE
|
||
|
||
Show man page for pdfman:
|
||
|
||
