PGTKM/Lassen version 0.9

This directory contains source code for the PGTKM/Lassen
Tcl/TK shell program. 

A simple example script is included in pgtkm.init much more
sophisticated examples are available to Sequoia 2000 participants. 
One version of the complete Lassen is in /pub/sequoia/src on 
s2k-ftp.cs.berkeley.edu. The programs in this distribution provide
more recent versions of some of those files.

To compile this program you will need access to the
Tcl/Tk libraries and the POSTGRES libpq library. 

The program has been tested using Tk v3.6 and Tcl 7.3, and the
libraries are expected to be in /usr/local/lib/tk and
/usr/local/lib/tcl -- though that can be changed using the TCL_LIBRARY
and TK_LIBRARY environment variables.

More complete descriptions of the PGTKM program and the new Tcl/Tk
commands it implements may be found in the man directory. 
(Note however that the z39.50 commands are not implemented for
this version).

The pgtk.init file contains some sample Tcl code using the database
functions.

There will be Sequoia technical report on Lassen appearing on an
FTP site near you before too long.
