1. Installation

	You should only have to do the following

		./configure
		make
		make install

	Look at the file INSTALL for details.

	A few hints:

		o 	You probably have to use g++ instead of c++ if
			you're compiling for Solaris:

				setenv CXX g++

			(before running ./configure, and be sure to remove the
			 file config.cache)

		o	You will also have to use gmake, rather than make:

				alias make gmake

		o	Optimization:

				setenv CXXFLAGS '-03'

		o	If you want to install locally (not as root), try

				./configure --prefix=<dir>

			where <dir> is where you want to install, such as
			<dir>=/home/logg/local .

-------------------------------------------------------------------------------
2. Testing

	Go to src/demo and run

		./tanganyika-demo

	This will solve the simple system

		u_1' = u_2
		u_2' = -u_1

	on [0,100] with initial conditions u(0) = (0,1), for which
	the solution is u(t) = (sin(t),cos(t)). Then start Matlab
	and type

		tanganyika_demo

	This will generate a few plots and some comments.

3. Feed back

	I would be glad to receive some feed back on the code. If you manage
	to install the library, please send me a note on this. Just copy
	the following into an xterm:

	uname -a | mail -s "Tanganyika 1.2.0 installed" logg@math.chalmers.se

	If something doesn't work or could be done better, tell me about it,
	or send me patch.
