How to install:
Gunzip and untar the package:
gzip -dc trap_1.0.tar.gz | tar xvf -
(this will create a directory named trap).
Move your trap directory to the selected location on your server disk. You may need to have administrator privileges to do it.
mv trap /selected_directory
Put the trap directory on your path or, alternatively, make a symbolic link to the trap executable on a directory which is already on the path.
Enjoy your TRAP (the software!).
