	------------------------------------------------------------------------
	This program installs the EchoIRLP software and sets up your EchoIRLP
	parameters. 

        Requirements:
        You must have IRLP installed and fully functional.
        You must have previously registerd the intended callsign and password
        with EchoLink.

        NOTE: The IRLP volunteer support team WILL NOT provide support after
              installing EchoIRLP.

	NOTE: You must have installed the GNU GCC compiler and the rest of the
	      Linux development subsystem. If they are not already installed,
	      this installation script will attempt to install them for you.
	
	NOTE: The prefered option is capitalized on (y/n) questions. When an
	      option shows a default value, pressing the enter key will
	      automatically use the default value. Case sensitive items will be
	      shifted to the correct tense by the install script.
