# 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.
