+	  1) first, create a local monotone database that you can put
+	     wherever you wish:
+	        mtn db init --db=/path/to/pipo.mtn

+	        mtn pull ipnvcs.in2p3.fr --db=/path/to/pipo.mtn NPTool.dev
+	        mtn pull ipnvcs.in2p3.fr --db=/path/to/pipo.mtn NPTool.pro
+

+	     for the developement or production:
+	       mtn checkout --branch=NPTool.dev
