     library(lists)
     DOES NOT WORK YET => removed from start.pl and Makefile
right_chart_array.pl seems to run out of memory => removed from start.pl
     and Makefile

added more examples to Hdrug/LexRules/suite.pl

file hdrug/LexRules/decl.pl added another tree-like printing mode
`dt' that is to be used for derivation trees built by hc_d parser.
Added more examples Hdrug/LexRules/suite.pl
Added comments Hdrug/LexRules/PG/bug_dd.pl

Added possibility to view lexical entries in Hdrug/LexRules
       /start.pl
       /lr.tcl
       /decl.pl
Looked at time_out in st_tex.pl. It is still a mess, but at least
one example works that didn't before :-)

*** Tue Jul 12 11:34:13 METDST 1994

Added LexRules/PG/rcp3_dtrs which is rcp3 + construction of parse
trees (for use with Tree(d))

Added LexRules/PG/rcp3_d    which is rcp3 + construction of derivation
trees (for use with Tree(dt))

These are also added in LexRules/PG/Makefile and LexRules/start.pl

Added comments here and there, mainly LexRules/*

*** Wed Jul 20 10:48:39 METDST 1994

Changed Makefile.common so that re-building of single grammar is
possible

Changed hdrug.tcl bind <Return> into <FocusOut> in edit fields at
the bottom so that changes are properly communicated to prolog even
if no return is pressed. Changes from the command interpreter are
now also propagated to tk (changed in cmd.pl and library(tk_menu) ).

*** Fri Jul 22 11:36:51 METDST 1994

Added view option for arbitrary Prolog goals
hdrug.tcl tk.pl

*** Mon Jul 25 11:00:05 MET DST 1994

Added bindings for arrow keys for Entries

*** Fri Jul 29 09:36:10 METDST 1994

Changes in pretty printing of trees. Now the nodes of the
tree are buttons. An action can be defined (definition 
show_node(Name,Node) ) upon clicking such a button.

I completely re-did the way test-suite statistics are shown
in a TK widget. For this purpuse I have included the BLT package,
of which the graph widget is used.

The grammar CBCG now uses library(feature), in order to use e.g.
the pretty printing routines for matrices etc.

The *.tcl and *.bm files are now properly placed in the directory
$hdrug_library. The procedures from e.g. SP_qbox and SP_question are
now auto-loadable. 

Wed Aug 31 23:57:38 METDST 1994

Completely re-did directory structure. This should be easier to install
at other sites.

Also started with the manual. This has led in turn to numerous small 
changes. Most interface predicates are now optional; there are other hooks 
for parsing/generation. 

Put interpreters.pl inside go.pl. Put st_*.pl inside modules. Moved 
lex_string stuff into library, (it is not provided by default anymore).

Changed Dcg demo completely.

Changed almost anything..........................
stopped 

moved to ProTcl 1.3
