 separate scripts using the following scheme: mpbb-<step>. The steps that are
 needed to be executed to build are the following ones:
 
-    1. selfupdate --nosync
+    1. Update base without updating the portindex.
 
-       mpbb selfupdate --prefix /opt/local
+            mpbb selfupdate --prefix /opt/local
 
-    2. checkout ports tree (at specific rev, should update portindex)
