+# The body of this file contains a representation of a very small and contrived
+# kadm5_principal_ent_rec meant for fuzzing.  For fuzzing purposes, the smaller
+# the input, the better.
+#
+# To compile this input into a binary input file suitable for fuzzing:
+#
+#   cd build
+#   make -j4
+#   cd lib/kadm5
+#   make test_marshall
+#   ./test_marshall --in-text --byte-order-in=packed     \
+#                   --byte-order-out=packed              \
+#                   --out-hex                            \
+#                   kadm5_principal_ent_rec              \
+#                   ../../../lib/kadm5/fuzz-inputs-txt/test_marshall-ent0.txt
+#
+# then decode the hex (e.g., with xxd -r -p) and save it in a file.
+#
+# Currently we have that saved in lib/kadm5/fuzz-inputs-packed/.
+#
+# To build and fuzz with this input:
+#
+# cd build
+# AFL_HARDEN=1 make -j4 CC=afl-clang all
+# cd lib/kadm5
+# AFL_HARDEN=1 make -j4 CC=afl-clang test_marshall
+# rm -rf f; mkdir f
+# ../../libtool --mode=execute afl-fuzz \
+#               -i ../../../lib/kadm5/fuzz-inputs-packed \
+#               -o $PWD/f                                \
+#               ./test_marshall --byte-order-in=packed   \
+#                               --byte-order-out=packed  \
+#                               --out-hex                \
