- # This plugin is a small modification of the original diff_gnu.php plugin.
- # It allows use with safemode enabled. 
- # However it requires the directory where diff is located to be in the php ini
- # This way you can still control what programs are executed by PHP and the programs 
- # can have root as owner.
- # Of course its not smart to put the normal bin in your php settings, cause that
- # would effectively disable safemode, just copying the diff utility works best.
- 
- # Example phpsettings entry:
- #   safe_mode_exec_dir = /usr/local/bin/ewiki
- 
- # With safemode disabled it should work without any special settings.
- 
- # Original plugin comment:
- 
- # This diff plugin utilizes the external GNU diff program to show up
- # differences between two versions of a WikiPage.
- # The diff utility is commonly not part of the graphical OS simulators
- # from Redmond, but you could install the Cygwin environment to make
- # it available.
