# We have 3 lua versions on SBo: lua is v5.1, lua52 is 5.2, lua53 is 5.3.
# Wireshark only supports 5.1 and 5.2, not 5.3. The lua version doesn't
# affect core wireshark, only 3rd-party plugins written in lua. Most
# plugins should work with either version, but at least one (2ping.lua)
# fails with 5.1. There are also probably some older plugins written
# for 5.1 that would fail with 5.2. So we support both versions here.
# There are 2 possible settings for LUA52:
# - yes (default): use lua52 if it's installed, fall back to lua otherwise.
# - no: don't use lua52; always use lua.
