NOTES ON INSTALLATION, ETC

This has been installed on two UNIX sites, and should be moderately
easy to install on other UNIX sites.

It is assumed that there is a set of directories all at the same
level: sticke, cgi-bin, tmp.
In addition there will be a directory, also at the same level, for
each set of stick-e applications (often this will be a symbolic link
to some other directory).

The sticke directory contains general HTML files that are of use to all
applications; in particular it contains a file launch.html, which
launches the applications; new applications need to be plugged into
this script.

The $DIR (set at launch) directory contains the application (it should
take the form ../YYY).  In addition $APP (also set at launch) contains
the name of the application.  If the $APP is XXX, then the YYY directory
should contain XXX.notes, XXX.notes.form.html (a menu -- this can be
generated automatically from the world context in XXX.notes by using
setrigger -h -m XXX.notes) and XXX_map.gif.  In addition it should contain
entities.sgml, which defines any extra SGML entities used.

There should be a file called "client" in cgi-bin, which is a link
to the stick-e client program.

All these directories, files, links, etc, must, of course, be visible from
the WWW server.

Some of the cgi-scripts use perl, which is assumed to be in /usr/local/bin/perl.
The perl scripts have some security checking to make sure they are
running on a designated server; any new sever server needs to be added to
the "referers" list.  The mailing script sends mail to $CONFIG{'recipient'}.

The scripts in cgi-bin, of course, need to have full execute permission, and
all files need to have full read position.  The tmp file needs to have full
read, write and execute permission. All intermediate directories need to
have full read and execute permission.

This whole web application is of a pre-prototype nature: it assumes a
single user at any one time, and records the user's state in the
setrigger server (which runs continually in the background from the time
an application is launched until it is killed), and in a <form> that is
put in the tmp directory.

The maps script uses the ucb version of the UNIX expr command.
