+# GPT Partition table patterns.
+# Author: Rogier Goossens (goossens.rogier@gmail.com)
+# Note that a GPT-formatted disk must contain an MBR as well.
+#
+
+# The initial segment (up to >>>>>>>>422) was copied from the X86
+# partition table code (aka MBR).
+# This is kept separate, so that MBR partitions are not reported as well.
+# (use -k if you do want them as well)
+
+# First, detect the MBR partition table
+# If more than one GPT protective MBR partition exists, don't print anything
+# (the other MBR detection code will then just print the MBR partition table)

+# The following code does GPT detection and processing, including
+# sector size detection.
+# It has to be duplicated above because the top-level pattern
+# (i.e. not called using 'use') must print *something* for file
+# to count it as a match. Text only printed in named patterns is
+# not counted, and causes file to continue, and try and match
+# other patterns.
+#
+# Unfortunately, when assuming sector sizes >=16k, if the sector size
+# happens to be 512 instead, we may find confusing data after the GPT
+# table... If the GPT table has less than 128 entries, this may even
+# happen for assumed sector sizes as small as 4k
+# This could be solved by checking for the presence of the backup GPT
+# header as well, but that makes the logic extremely complex
