   2 # Compile latex document and open viewer at specified location via synctex
   3 # latexmk (included in texlive-bin) and wmctrl are used by the script. wmctrl
   4 # is used to give evince focus after updating the document, you don't have to
   5 # install it, if you don't want this functionality.

   7 # latexmk is used to compile document - it should automatically
   8 # compile your document multiple times and run bibtex as required.
   9 # You have to tell latexmk to use the --synctex=1 option when running
  10 # pdflatex, to do so, create a file ~/.latexmkrc containing:
  11 #       $pdflatex = 'pdflatex --interaction nonstopmode --synctex=1 %O %S';
  12 # There must be a newline after this line. I havent found any way to
  13 # give this info to latexmk directly from the commandline, but that
  14 # would be alot easier.
  15
  16 # To get AUCTEX to use this scipt, add the following lines to your .emacs file:
  17 # You can then use C-c C-c Synctex RET to compile and view in evince
  18 #        (eval-after-load "tex"
  19 #            '(add-to-list 'TeX-command-list
