#    MakeIntRetags v4_9_0: 4.9.0.retags
#
# will retrieve v4_9_0 tags from amongts 4.9.0, 4.9.0preN and 
# 4.9.0intN tags.  While
#
#   MakeIntRetags v4_9_0 4.9.0x.retags
#
# will contain the pre and int tags as well.
#
# Only add packages tagged on the head by default if
# <release>.newrel is revision 1.1 in repository.
#
# Add packages which, by default are to be tagged on the HEAD
# of the repository ( the latest revisions ).  These will be
# processed such that any REAL tag will override them.
