        Skeletal instructions for using the contents of this tar file
		(for info 4.1 WJS.  Aug 10)

	info 4.1 adds the REMOTE_TRADITIONAL info source.  
Those sites that have defined the JGOFS configuration
parameter INFOSERVER will probably get better results by using
REMOTE_TRADITIONAL instead of TRADITIONAL (see note, below; near bottom).  
If you would like to use this feature, you need to use at least 
build-env.pl v 1.3a, which configures for it.
	info 4.1 changes the names of some of the environment variables
controlling logging.  The old names are still accepted.  If you
wish to use the new logging environment variable names, 
and if your present build-env.pl file does NOT mention them, you will
need an upgrade to build-env.pl, found as part of the  build  JGOFS utility.

	info 4.0b fixed a bug which cause info to fail in a web
environment if info was invoked from a JGOFS page with an associated
selection/projection string.

	info 4.0a removes leading and trailing blanks from info's
control keywords

	info 4.0 is a re-write of info to increase robustness.
Also, a design change was made to allow more precise control over
which data info should present to the user.  Please see the info.doc
file in this release for details.
	info 4.0 requires a newly released JGOFS utility called
perl_utils.
	info 4.0 requires the parse_path_info program found in
the JGOFS path_info utility.  It is possible
but unlikely that this utility is already installed on your system.
	info 4.0 can be controlled by the same build-env.pl parameters
(USEDATABASE or INFO_USEDATABASE) as the previous version of info.  It
also has a new set of controlling parameters.  Old and new are described
in info.doc.  If you wish to make any modification to the defaults,
and if your present build-env.pl file does NOT mention them, you will
need an upgrade to build-env.pl, found as part of the build JGOFS utility.
	The latest versions of all 3 of the above utilities can be found
on the same ftp site from which info was presumably downloaded.

	Indirectly related to info 4.0 is the fact that there is
a bug in one of the library functions needed by an option of the 
parse_path_info program used by info.  In particular, the library
function path_info_routines must be at at least version 1.4a.
path_info_routines is found in the libupd utility - check the ftp
site for appropriate versions (more exact information not available
at the time this is being written)	


	The file jgofs_root/src/htmlbin/makefile.aaserv, if present,
must be modified so that it does not try to create an older version of info.
Replace the lines
		SCRIPTS = ${HTMLBINDIR}/dir   \
			  ${HTMLBINDIR}/info
with the line
		SCRIPTS = ${HTMLBINDIR}/dir
This line should start in column 1, despite the way it is shown above.
It is probably also advisable to remove or rename the old info source,
jgofs_root/src/htmlbin/info_pl.tmp

	To install info 4.0 for the first time, determine which of the 
above utilties will be required (perl_utils, at least, will be needed).
Each package has its own installation instructions (and the general
build instructions has information about each package as well).  
	The build package (if needed) should be installed before the path_info
package (if needed).  If the build package is installed, the safest thing
to do is to rebuild the whole server.  However, if you are sure that
new and old build-env.pl files differ only by the parameters related to info,
you might be able to get away without rebuilding.
 

=====

Note regarding historical use of info on data servers with defined
INFOSERVER JGOFS configuration parameter 
	The JGOFS configuration parameter INFOSERVER caused many
requests for info to go to a server on a system other than the data server, 
NOT the info program installed on the data server.  If by chance a request
was made to the info program installed on the data server, the response
was typically a "no data" response.
	By default, info v 4 will act the same way.  Using the
REMOTE_TRADITIONAL parameter is an enhancement that allows requests made
to the local info program to be referred to the appropriate remote server.
