+# This script is used to resolve various flags that appear on "show sess all".
+# All identified ones will be appended at the end, with a short name and their
+# value, followed by either the value resolved by "flags" when it's found, or
+# by the copy-pastable command to use to resolve them. The path to FLAGS is
+# searched in this order: 1) $FLAGS, 2) in the path, 3) dev/flags/flags, 4)
+# in the same directory as the script.
+#
+# This script is horrendous, but it's not a reason for making it even more
+# disgusting. The big regex flag mapping mess at the end is readable on a
+# large screen and it's easier to spot mistakes using this aligned format,
+# so please preserve this as much as possible and avoid multi-line formats.
+#
+# The append_* functions provide different variants that are still commented
+# out. It's mostly a matter of taste, they're equivalent.
+#
+# Usage: socat /path/to/socket - <<< "show sess all" | ./$0 > output
+
+# look for "flags in path then in dev/flags/flags then next to the script"
