 The start-tor-browser script that comes with the Linux Tor Browser Bundle
 package fails if a symlink is created that points to it and the symlink
 then executed instead of the actual script.

 For example, I installed the bundle in ~/apps/ but I have ~/bin/ in my
 $PATH so I symlinked the startup script in ~/bin/:
 tor-browser -> ../apps/tor-browser_en-US/start-tor-browser

 However, this messes up the startup since the script assumes now that it's
 located in ~/bin instead of ~/apps/tor-browser_en-US/

 Below is a patch for the start-tor-browser script that fixes this issue:

 {{{
 19c19,25
 < mydir="$(dirname $0)"
 ---
 > if [ -L $0 ]; then
 > appname=$(readlink -f $0)
 > else
 > appname=$0
 > fi
 >
 > mydir="$(dirname $appname)"
 }}}
