<p>
3/6 (AR) The format <tt>.gfe</tt> defined to support
<b>grammar writing by examples</b>. Files of this format are first
converted to <tt>.gf</tt> files by the command
<pre>
gf -makeconcrete File.gfe
</pre>
See <a href="../lib/resource/doc/examples/QuestionsExI.gfe">
<tt>../lib/resource/doc/examples/QuestionsExI.gfe</tt></a>
for an example.
<p>
31/5 (AR) Default of p -rawtrees=k changed to 999999.
<p>
31/5 (AR) Support for restricted inheritance.
31/5 (AR) Support for restricted inheritance. Syntax:
<pre>
M -- inherit everything from M, as before
M [a,b,c] -- only inherit constants a,b,c
M-[a,b,c] -- inherit everything except a,b,c
</pre>
Caution: there is no check yet for completeness and
consistency, but restricted inheritance can create
run-time failures.
<p>
29/5 (AR) Parser support for reading GFC files line per line.
The category <tt>Line</tt> in <tt>GFC.cf</tt> can be used
as entrypoint instead of <tt>Grammar</tt> to achieve this.
<p>
28/5 (AR) Environment variables and path wild cards.
GF_LIB_PATH and GF_GRAMMAR_PATH.
<ul>
<li> <tt>GF_LIB_PATH</tt> gives the location of <tt>GF/lib</tt>
<li> <tt>GF_GRAMMAR_PATH</tt> gives a list of directories appended
to the explicitly given path
<li> <tt>DIR/*</tt> is expanded to the union of all subdirectories
of <tt>DIR</tt>
</ul>
<p>
26/5/2005 (BB) Notation for list categories.
