This directory contains the external image viewer XV, which can be
used to view pictures in acedb.

Please read the file XV.License.  According to this we are required to
make all the files in the distribution available if we redistribute
XV.  The archive xv-3.10a.tar.gz contains the entire XV source code
and documentation.

To make life easier for ACEDB users, we also provide ready compiled
executables for SUN, OSF and SGI (Irix 5).  To install one of these,
do the following:

  - Transfer the file for your machine type xv.???.Z
  % uncompress xv.???.Z
  % mv xv.??? xv
  % chmod 755 xv
  - Make sure this xv is in your path.  Ideally, get root access and
	move xv to /usr/local/bin, where it will in the standard path
	of most users.
  % rehash

Now test it by going to your acedb home directory after installing
update 4-8, and type:

	xv pictures/zk637_8_dvl.jpeg

See the file /pub/acedb/celegans/PICTURES.doc on this site for
further details on how to access the pictures from ACEDB.

NOTE: the file $ACEDB/wscripts/display_script has to be executable.
If you used an old version of the INSTALL script it will not be.  To
make it executable do "chmod 755 $ACEDB/wscripts/display_script".
