TO DO List

Add a "root" option -- similar to "absolute" except that a root
directory may be specified instead of the current directory being used.
-- helpfull when setting up a package in /tmp  i.e.:  /tmp/usr/sbin/fixperms
   root would be set to /tmp and fixperms would save the package as
   /usr/sbin/fixperms instead of /tmp/usr/sbin/fixperms

Add receiving lists of files through stdin.
