I. CHANGES FROM UPSTREAM

Latexmk almost works out of the box.  Three changes have been made to

conform to Fedora Core conventions.  First, the default DVI, PostScript,

and PDF previewers have been changed to 'xdg-open'; see below for more

information. Second, the script has been altered so that it does not

search for the perl binary; perl is in a known location on Fedora Core

systems.  Finally, the site-wide configuration file is /etc/latexmk.conf

only, as opposed to the list of names searched by the original latexmk.

II. PREVIEWERS

The command xdg-open views a file using the viewer selected by the user

for that type of file.  See the xdg-mime(1) command for more

information.  Unfortunately, the use of xdg-open precludes the updating

of the previewing application, as latexmk cannot know which application

is doing the previewing.  It also breaks viewing of landscape documents

for some previewers.  For best results, you should customize latexmk for

the particular previewers you intend to use.  Following are the settings

for some commonly used previewers, to be placed in the site, user, or

project configuration file.  Note that an update method of 1 means that

there is no way for latexmk to cause the program to refresh; you have to

take some action of your own to see changes to the document.

   A. DVI PREVIEWERS

      1. xdvi

         $dvi_previewer = 'start xdvi';

         $dvi_previewer_landscape = 'start xdvi -paper usr';

         $dvi_update_method = 2;

      2. pxdvi

         $dvi_previewer = 'start pxdvi';

         $dvi_previewer_landscape = 'start pxdvi -paper usr';

         $dvi_update_method = 2;

      3. kdvi

         $dvi_previewer = 'start kdvi';

         $dvi_previewer_landscape = 'start kdvi';

         $dvi_update_method = 0;

   B. POSTSCRIPT PREVIEWERS

      1. gv

         $ps_previewer = 'start gv -watch';

         $ps_previewer_landscape = 'start gv -swap -watch';

         $ps_update_method = 0;

      2. evince

         $ps_previewer = 'start evince';

         $ps_previewer_landscape = 'start evince';

         $ps_update_method = 1;

      3. kghostview

         $ps_previewer = 'start kghostview';

         $ps_previewer_landscape = 'start kghostview --orientation=landscape';

         $ps_update_method = 1;

         If you can remember to set the "Watch File" option in

         kghostview, then instead set:

         $ps_update_method = 0;

         Unfortunately, there appears to be no command line argument to

         set the "Watch File" option.

   C. PDF PREVIEWERS

      1. gv

         $pdf_previewer = 'start gv -watch';

         $pdf_update_method = 0;

      2. evince

         $pdf_previewer = 'start evince';

         $pdf_update_method = 1;

      3. kghostview

         $pdf_previewer = 'start kghostview';

         $pdf_update_method = 1;

	 See the remark on the "Watch File" option above.

      4. kpdf

         $pdf_previewer = 'start kpdf;

         $pdf_update_method = 1;

	 The "Watch File" remark above for kghostview applies to kpdf also.

      5. acroread

         $pdf_previewer = 'start acroread';

         $pdf_update_method = 1;
