    Important notes:
    ================
-   *CUPS-PDF requires root privileges since it has to modify file ownerships. 
-    In recent distributions the "RunAsUser" option in cupsd.conf is set to 
-    "Yes" which removes these privileges. Please make sure to set 
-    "RunAsUser No" if you want to use CUPS-PDF.
-    *** Starting with version 1.2.0 CUPS implements the "RunAsOption" no 
-        longer. In order to ensure CUPS-PDF is running with the required root 
-        privileges you have to make 'root' the owner of the cups-pdf backend 
-        and set the file permissions of the backend to 0700 (root only).
-   *make sure if any of CUPS-PDF's working directories (e.g. output) is a 
-    NFS mounted volume it is mounted without root_squash!
-   *CUPS-PDF is known to fail if the gs (GhostScript) binary on a system is 
-    compressed by upx (Ultimate Packer for eXecutables).
-   *if you are using SELinux make sure it does not interfere with CUPS-PDF
-    (you can disable SELinux for CUPS by "setsebool -P cupsd_disable_trans 1"
-     or have a look at contrib/SELinux-HOWTO to make it work)
