Untar twinlib.0.3.tgz somewhere. Now you must compile the library by typing 'make' ; type make install to install it.
To have the example, type 'make example'. You should launch ./example to see some examples.

If you want to desinstall TwinLib, just type make uninstall.

I had tested it on a RH and Mandrake on x86, all seems to work correctly (don't forget to install tmake, and to set TMAKEPATH and QTDIR !) There is the var PATHLIBS in the Makefile, it's the path to install TwinLib. If the example don't work because it doesn't find the lib, /sbin/ldconfig should be launched.
