***********************************************************************
SNNSv4.2 is now ready to be compiled. Please read carefully all
warning and error messages above if there are any of them. Please
refer to the file Readme.install if you see any problems.

You can now

make compile      to compile all parts of SNNS
make install      to compile, strip, and install all parts of SNNS
make clean        to cleanup all source directories after installation
make uninstall    to remove all installed parts of SNNS

For your convenience the following sub targets exist for the top level:

make install-tools    (implies compiling the kernel)
make install-xgui     (implies compiling the kernel)
make install-man

make clean-kernel
make clean-tools
make clean-xgui

make uninstall-kernel
make uninstall-tools
make uninstall-xgui
make uninstall-man

After installation the programs can be found in
    /home/pbulk/work/math/snns/work/SNNSv4.3/xgui/bin/x86_64-pc-solaris2.11    (xgui)
    /home/pbulk/work/math/snns/work/SNNSv4.3/tools/bin/x86_64-pc-solaris2.11   (tools)

And now: Good luck and have fun!
