Copy the source to a local directory and add 'bin' to PATH.
In order to use AWS related commands, you will need to create a directory ${HOME}/.tool and add your AWS private key and cert files to it. If such a directory by some other name already exists, you could also set an environment variable TOOL_DIR to point to it.
This command line intends to be self documenting. To begin, simply type "tool".
Example:
$ tool
Usage:
tool aws ...
$ tool aws
Usage:
tool aws database ...
tool aws instance ...
tool aws role ...
