# at this point, we create two assoc. arrays to hold
# the filenames:
#     allFilesPerforce - from "p4 fstat //myclient/..."
#     allFilesPresent  - from "File::Find" mechanism
# We can walk through the two lists of files to find
# what's missing (and probably why).
#
#
# (note that we massage the path-separator to be '/'
# in all cases, mapping \\ to / in the pathnames.
# That's a marginal portability hack to make these scripts
# work on Unix/Linux and Windows fairly happily.)
