xfree86-common 4.3.0.dfsg.1-6ubuntu25 (i386 binary) in ubuntu warty

X Window System (XFree86) infrastructure
 xfree86-common contains the filesystem infrastructure required for further
 installation of the X Window System in any configuration.
 .
 Those wishing an X server only (with remote font services and clients) will
 also require the xserver-common package and an X server package (most
 likely xserver-xfree86).
 .
 The counterpart to the above configuration is a machine with the X libraries
 (the xlibs package), xbase-clients, a window manager, some X font packages,
 and likely many more client packages.
 .
 Those who desire a standalone X workstation (and/or are fuzzy on the concepts
 of X servers and X clients) will require both of the above sets of packages.
 For convenience, the "x-window-system" metapackage will include everything
 that is required for a standalone X workstation.
 .
 A number of terms are used to refer to the X Window System, including "X", "X
 Version 11", "X11", "X11R6", and "X11R6.4". The version of X used in Debian
 is derived from the version released by the XFree86 Project, Inc., and is
 thus often also referred to as "XFree86". All of the preceding quoted terms
 are functionally interchangeable in a Debian system.
