Contents of tcl_tk_blt.tar
--------------------------

This package contains the source code for
	Tcl 8.3.2
	Tk  8.3.2
	BLT 2.4u
and an automatic build script called build_tcltkblt.sh

The Tcl/Tk distributions were obtained from
	http://www.scriptics.com/software/tcltk/choose.html
At the time of writing Scriptics recommend 8.3.3 as the most recent stable
release, however on some platforms I have encountered problems when this
version is linked with BLT.

The BLT distribution was obtained from
	http://www.tcltk.com/blt/
At the time of writing 2.4u is the recommended version and is compatible
with Tcl/Tk 8.3.

NOTE that the blt2.4u/src/shared/Makefile.in has been modified from the
official version, to add missing targets which otherwise cause "make install"
to fail - see
	http://www.ccp4.ac.uk/ccp4i/install_tcltkblt.html#blt_make_install

How to build and install from this distribution
-----------------------------------------------

The script "build_tcltkblt.sh" which will try and automatically
build the three packages for you.

NOTE THAT YOU MUST EDIT THIS SCRIPT TO SET THE FOLLOWING VARIABLES:
	ROOT = the directory containing this script and the tcl/tk/blt
	       directories
	LOCAL= the place you want to install the packages

Also you must set the CC variable if you wish to use a different C compiler to
"cc".

Then execute the command ./build_tcltkblt.sh to start the automatic build.

If you wish to build the packages yourself then look at the README and INSTALL
files in each subdirectory, and see
	http://www.scriptics.com/doc/howto/compile.html
