DESCRIPTION

       mongo  is  a JavaScript shell (with GNU readline capabilities).	It supports interactive and non-interactive use.  When used interactively,
       JavaScript can be used to query the database or perform any other function normally available with SpiderMonkey.  Database output  is  dis-
       played in JSON format.

       If JavaScript files are specified on the command line, the shell will run non-interactively, running each one in sequence and then exiting.

       mongo 192.169.0.5/foo
	      start the shell using the foo database at 192.169.0.5:27017

       mongo 192.169.0.5:9999/foo
	      start the shell using the foo database at 192.169.0.5:9999

       mongo script1.js script2.js script3.js
	      run three scripts and exit
