    14 # Description: 

    15 # unsplitdirs utility

    16 # This utility converts a directory tree which may contain "splits" due to case inconsistencies into

    17 # a combined form.  This is best illustrated as follows:

    18 # epoc32/RELEASE/ARMV5/urel

    19 # epoc32/Release/armv5/UREL

    20 # epoc32/RELEASE/armv5/Urel

    21 # are "healed by this script into:

    22 # epoc32/RELEASE/ARMV5/urel  (i.e. the first occurrence.

    23 #

    24 

    25 #

    26 # Files within these directories are maintained. i.e. it is possible to fix 

    27 # a directory tree with files already left in it.

    28 #
