# Description: 
# unsplitdirs utility
# This utility converts a directory tree which may contain "splits" due to case inconsistencies into
# a combined form.  This is best illustrated as follows:
# epoc32/RELEASE/ARMV5/urel
# epoc32/Release/armv5/UREL
# epoc32/RELEASE/armv5/Urel
# are "healed by this script into:
# epoc32/RELEASE/ARMV5/urel  (i.e. the first occurrence.
#

#
# Files within these directories are maintained. i.e. it is possible to fix 
# a directory tree with files already left in it.
#
