+This script implements the SSDT branching strategy based on hg flow.  
+
+The intension is to reduce dudgery of creating release branches.  The 
+script tries to do the right thing based on standard SSDT project structures, 
+but it is the user's responsibility to ensure it's correct.
+
+The script does NOT "hg push --new-branch".  That step is left for you
+if the branch was created correctly.
