+* Infocenter home (IHOME) at /home/infocenter/latest
+  - Scripts checked out at $IHOME/bin
+  - Deployable doc plugins at $IHOME/deploy
+* Cronjob created to execute doit_nightly.sh
+    ssh dsdp.eclipse.org -l infocenter
+    crontab -e
+    #Run the doc update at 2:00 every weekday
+    0 2 * * 1-5     /home/infocenter/latest/bin/doit_nightly.sh
