Under construction.

There are 3 different possibilities: compilation with TCL in tk
directory, in separate directory and with Perl.

Under TCL in tk directory
~~~~~~~~~~~~~~~~~~~~~~~~~
You can just replace the standard tkText* files with the
supplied, and link wish with one additional file ptclGlue.o.

For this copy all C files (*.c *.h) from the root directory of
distribution into tk directory and add ptclGlue.o to the list TEXTOBJS
in the Makefile.

	make 
	./wish ROOTDIR/demo/etext.tcl

will give you a sample window into which you can type some minimal
math. See documentation in etext/doc.

Under TCL in separate directory
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If you want to live in a separate directory, make sure that the links
tk and tcl in this directory are OK, and essentially do

	cp Makefile.etext Makefile
	make
	./wish demo/etext.tcl

(See README.etext for keybindings).

Unfortunately the supplied Makefile is not autoconf'ed, so probably
you need to 

	cp tk/Makefile Makefile
	patch <Makefile.diff
	make
	./wish demo/etext.tcl

I'm not sure that there is no rejects from patching :-(.

Under Perl
~~~~~~~~~~

You need a recent Perl (5.003+ ?) and latest Tk/Perl. To install Perl,
get it from CPAN and

	./Configure -des -D CC=my_compiler -D prefix=/path/to/install/location
	make
	make test
	make install

Install Tk40*.* (or have it installed):

	perl Makefile.PL
	make
	perl -Mblib basic_example
	make install

Now you can compile eText. There are two variants. Either you do it in
independent directory:

	cd ROOTDIR/etext/eText
	perl -Mblib=/path/to/Tk-build-tree Makefile.PL
	make
	make test
	make install

(If you do not have Tk installed, you can run the test as

	perl -Mblib=/path/to/Tk-build-tree -Mblib t/eText.t

);

or you move etext/eText directory to reside in the main Tk build tree,
and rebuild Tk:

	mv ROOTDIR/etext/eText ROOT_TK_DIR
	cd ROOT_TK_DIR
	perl Makefile.PL
	make

To test the extension do

	perl -Mblib -I eText/utils eText/t/eText.t

Now, when you install Tk by doing

	make install

eText will be installed as well.

Currently you need to have Tk build tree around to build eText.

make test gives you a window with some example. See README.etext and
documentation in doc for key bindings.

REMARK
~~~~~~

If you have an older Tk (before 401.000), you will see a warning like
this: 

"tkText.c", line 998: warning: argument #2 is incompatible with prototype:
        prototype: pointer to function(pointer to void) returning void : "unknown", line 0
        argument : pointer to function(pointer to char) returning void
