		Installation of web interface to statisticker. WJS Sep 03
				(Mod Jul 04 reflecting changed distribution)
				(Mod Jul 05 reflecting changed build stuff)

	Knowledge of the JGOFS software setup is assumed.  Relative file
specifications in this document are relative to the JGOFS root of the
server under discussion.  The "." directory in this document represents
the directory in which the statisticker web interface is installed.
"/jg" represents the directory on disk corresponding the cgi-bin
directory definition of the web server on which the interface is installed.
	Special comments are made relating to "other option servers" 
("OOservers") - said comments are not part of the requirements of the 
statisticker web interface.

	The major components are the interface module, stat_web_interface.pl,
and the statisticker method.  The latter is distributed as its own tar file.
	The interface module needs to be installed with x file access for
its intended users.  Typically, the module is pointed to from a web page,
which forces its placement into the cgi tree defined in the configuration
of the web server that is the target of the web page's link.  In the
JGOFS system, this is the tree descending from the "/jg" directory;
typically, the interface is placed in the "/jg" directory itself.

	The interface module is intimately connected to the statisticker
method itself.  Those connections are described in the interface code.
In addition, the interface module makes the following configuration assumptions:
1) The existence (and x file access) of /usr/bin/perl and perl
   modules ctime.pl and cgi-lib.pl.
2) There is an object definition in the objects/.objects file for
   an object named "statisticker" using to the statisticker method.
   It is recommended that this definition repress all the buttons except
   "Plotting and other operations" and "Flat".
 Sample:
   statisticker=optstats DIRLINK=FALSE DOCLINK=FALSE LEV0LINK=FALSE LEVNLINK=FALSE
3) There is an object definition in the toplevel .objects directory for
   an object named "test".  The data, variables, etc in this object should
   be irrelevant to the statisticker interface
4) The existence (and x access) of "standard" JGOFS utilities bin/list 
   and bin/listvar [sic - the bin directory is in all servers.  The optbin
   directory of an OOserver corresponds to the htmlbin directory of a "data"
   server]
5) The existence (and x access) of configuration routine ./build-opt-env.pl
   This routine establishes an environment in a fashion similar to
   opt-build-env (an OOserver analog to a data server's build-env.  At
   present, there is no data server analog "build-env.pl").  The
   "opt" in this name may be the only dependency of the web interface
   module being designed for OOservers.
6) The existence (and x access) of the "standard" JGOFS program ./serv
7) The string "nd" represents missing data

	Installation consists of installing the method (documentation in
its tar file), going through the configuration assumptions above and
making the appropriate modifications, and (most likely) creating a link
to the interface module from someplace else.  For the current OOserver,
this link is made in the otheropt file found in the "/jg" CGI directory.
Sample link (from a version of that file):
	<a href="/jg/stat_web_interface.pl$OBJEXT?$SUBSELS">Statistics</a>
