=head1 NAME
interchange - an e-commerce and general HTTP database display system
interchange [--options] [file]
=head1 VERSION
Interchange is a database access and retrieval system focused on e-commerce.
It allows customers to select items to buy from catalog pages. The program
tracks user information in sessions and interacts with an HTTP server
through sockets.
Interchange has many, many, functions and features; they are too numerous
to describe in this venue. Complete information can be found at
its web site:
Interchange requires Perl 5.005 or higher; more information on Perl can
be seen at:
=head1 OPTIONS
Interchange uses the Getopt::Long module, and most options will be recognized
if they uniquely identifiable. The canonical forms are:
=over 4
=item C<-a, --add>
Add a catalog to the system. Information taken from the input file
(or standard input). Implies reconfig=catalog. Example:
echo "Catalog simple /catalogs/simple /simple.cgi" | bin/interchange -a
The information is in the form of a standard Interchange catalog line,
and must be in the single-line format.
=item --runjobs=catalog[=job]
Run a jobs group which is a series of files in a directory with
the name corresponding to the C<job>. For instance, if you
set up a directory called "weekly" in your pages directory
for the catalog C<foundation>, you can run those files with:
interchange --runjobs=foundation=weekly
Files ending in .html (or whatever HTMLsuffix is for that catalog)
are skipped. It is not tree-recursive -- directories are ignored.
Results can be emailed to an address if you specify --email=address,
and they will be put in the jobs log file.
Alternatively jobs can be specified with --jobgroup=jobname B<before>
the --runjobs option. In other words, this will work:
interchange --jobgroup=weekly --runjobs=foundation
This will NOT work:
interchange --runjobs=foundation --jobgroup=weekly
=item -d dir, --dir=dir
Directory for VendRoot. This is where the Interchange configuration file
will be looked for (if not redefined with C<-f>), and where the log file
will go (if not redefined with the ErrorFile directive).
=item -e name, --exclude=name
Exclude catalog from this startup.
=item -email=address
Email address to email jobs results to.
=item -f file, --config=file
Configuration file to use (default is interchange.cfg in VendRoot).
=item -h, --help
Display help on command line options.
=item -i, --inetmode
Run with internet-domain socket only. Normally Interchange runs with
both UNIX- and internet-domain sockets (except on Windows).
=item --jobgroup=job
Sets the job for --runjobs if that is not included in the --runjobs
call. MUST precede the --runjobs entry on the command line.
interchange --jobgroup=weekly --runjobs=foundation
See --runjobs for an explanation of what this does.
=item --kill [signal]
By default, kills the server ungracefully with signal KILL (9, usually).
The optional signal will be sent instead if supplied.
=item -q, --quiet
Suppress informational messages on startup. Only errors are shown.
=item --reconfig=name
Cause only catalog C<name> to re-read its configuration.
=item --remove=catalog
Remove a catalog from operation; any future requests will get a not-found
=item -r, --restart
Stop and restart the server. This may take a long time if many catalogs
are in use, and will temporarily take the system offline. If you want to
change a UserTag, use the --add option instead.
=item --serve
This is the default if no mode options (--reconfig, --kill, --restart, etc.)
are supplied.
=item --stop
Stop server gracefully with a TERM signal.
=item -t, --test
Report problems with config files; causes a complete configuration of
the Interchange server but no server start.
=item -u, --unix
Run with unix-domain socket only. Normally Interchange runs with
both UNIX- and internet-domain sockets. This will not work on Windows.
=item -v, --version
Display program version.
=item --DEBUG=1
Set to true value to run foreground in debug mode. It is normal to
receive warnings about various things if you run with perl -w.
=item Directive=value
Set a Interchange global directive upon start (or --restart). Example:
interchange SocketPerms=0666
This will start the server and override the default of SocketPerms or the
value set in interchange.cfg for this instance only. Any --restarts must
re-specify the directive if it is still to have that value.
=item name:Directive=value
Set a Interchange directive for catalog C<name> upon start (or --restart). Example:
interchange simple:VendURL="http://localhost/cgi-bin/simple"
This will start the server and override the default of VendURL for the
value set in catalog.cfg for this instance only. Any --restarts must
re-specify the directive if it is still to have that value.

print <<'END';

you are welcome to redistribute and modify it under the terms of the
GNU General Public License.
Command line options (first letter will usually work):
--add=catalog add a catalog to operation; parms taken from the
standard input as a "Catalog ..." directive
-d dir, --dir=dir directory for VendRoot (interchange.cfg, error.log, etc.)
-e name,
--exclude=name exclude catalog
--email=emailaddr Send results of cron job to emailaddr
-f file,
--config=file configuration file (default interchange.cfg)
--files spec filespec (perl regexp OK) for static page tree
-h, --help display this message
-i, --inetmode run with Internet-domain socket (TCP)
--jobgroup=jobname job group to run (hourly, daily, weekly, etc.)
--kill [signal] kill server ungracefully (9 or with optional signal)
-q, --quiet suppress informational messages on startup
--reconfig=catalog reconfig a particular catalog on the server
--remove=catalog remove a catalog from operation
--restart restart server
--runjobs=catalog[=job] run jobs for a particular catalog
(can use --jobgroup and -email)
--serve start server (default) (-start is alias)
--stop stop server gracefully
-t, --test report problems with config files
-u, --unix run with UNIX-domain socket
-v, --version display program version
--DEBUG=1 run foreground in debug mode

far the most prolific bug-finder. He also was primarily responsible for
