Switch_host is a tool that let you handle and configure a hostname lookup. Configuring the makefile, you tell switch_host what is the IP address to work with.
Switch_host is useful when you have a local server, and you want to use it either when you are at home or when you are out. Instead of modifing /etc/hosts by hand, switch_host will do it for you.

Usage: switch_host [options]

Options:
-a | --actual      Show current setting
-d | --dynamic     Set dynamic host
-h | --help        Print this message
-s | --static      Set static host
