-#
-# Example implementation for the Git filter protocol version 2
-# See Documentation/gitattributes.txt, section "Filter Protocol"
-#
-# The first argument defines a debug log file that the script write to.
-# All remaining arguments define a list of supported protocol
-# capabilities ("clean", "smudge", etc).
-#
-# This implementation supports special test cases:
-# (1) If data with the pathname "clean-write-fail.r" is processed with
-# a "clean" operation then the write operation will die.
-# (2) If data with the pathname "smudge-write-fail.r" is processed with
-# a "smudge" operation then the write operation will die.
-# (3) If data with the pathname "error.r" is processed with any
-# operation then the filter signals that it cannot or does not want
-# to process the file.
-# (4) If data with the pathname "abort.r" is processed with any
-# operation then the filter signals that it cannot or does not want
-# to process the file and any file after that is processed with the
-# same command.
-# (5) If data with a pathname that is a key in the DELAY hash is
-# requested (e.g. "test-delay10.a") then the filter responds with
-# a "delay" status and sets the "requested" field in the DELAY hash.
-# The filter will signal the availability of this object after
-# "count" (field in DELAY hash) "list_available_blobs" commands.
-# (6) If data with the pathname "missing-delay.a" is processed that the
-# filter will drop the path from the "list_available_blobs" response.
-# (7) If data with the pathname "invalid-delay.a" is processed that the
-# filter will add the path "unfiltered" which was not delayed before
-# to the "list_available_blobs" response.
-#

- # naturally contain a colon after the drive letter, so splitting by
- # colons simply does not cut it).

- # Detect semicolon-separated path list and handle them appropriately.
