 Tiki setup.sh - your options
 ============================

Composer: If you are installing via a released Tiki package (zip, tar.gz, tar.bz2, 7z), you can and should skip using Composer. If you are installing and upgrading via SVN, you need to run Composer after 'svn checkout' and 'svn upgrade'. More info at https://dev.tiki.org/Composer
  
 c run composer (log output on screen, not all warnings) and exit (recommended to be done first)
 L run composer (log output to logfile) and exit (recommended to be done first)
 V run composer (verbose log output on screen) and exit (recommended to be done first)

For all Tiki instances (via SVN or via a released package):

 f fix file & directory permissions (classic default)          o open file and directory permissions (classic option)
 S clear screen
