-# Acknowledgment:
-#  The following code is a modified version of an original work written by

-# Here are the ICA functions.
-# ---------------------------------------------------------------------------- #
-#
-# Here we prepare for the Iterative Comparison Analysis (ICA). Essentially, we
-# copy most of our chroot phase files to a new location then perform some
-# manipulations on the copied files to make diff comparisons easier. The steps
-# involved are:-
-#   (1) copy the whole tree (minus the PRUNEPATH defined below) to the CMP_DIR
-#       location. Use tar as it seems like the most appropriate tool for copying
-#       large directory trees around.
-#   (2) delete all symlinks.
-#   (3) gunzip all `*.gz' files.
-#   (4) delete all hardlinked files (of course trying to leaving the "master"
-#       intact)
-#   (5) convert all `*.a' files (ar archives) into a directory of the same name
-#       containing the unpacked object files.
-#   (6) fully strip the whole lot (but being careful to strip only the debug
-#       symbols from object `*.o' files).
