1) better integration to automake/autoconf/configure...
The rules are:
* by default look at -ltcl and -ltk
* you can specify --with-tcl and --with-tk to use
different versions, e.g. you can use --with-tcl=tcl80
and --with-tk=tk80 to use them.
* if your system has a dl library, it uses it, otherwise
not. This may cause problems if you have a -ldl, but
your tcl library doesn't need it :( There'll probably
be a --with-tcldl=no someday
2) make a few arrays bigger, particularily in the PDB interface.
3) type most of the numeric returns from the PDB, e.g.
a proc that returns a layer now returns `layer-#' instead
of just `#'. This may cause problems for scripts that
get an array and then iterate over it. (as in gimp-list-images
or similar)
4) consolio is now based on Jeff Hobbs `tkcon', much better than
the older one. And the license is much less restrictive.
5) The switch to tkcon unveiled several errors with the internal
packages, so I fixed most of them. Now sub-interpreters
can use the same PDB interface as the ``parent'' interp.
I should be able to make something akin to the script-fu
mechanism out of this... (someday)
