-- Test fixture for the cgit Lua filter API, exercised by t0201-filters.sh.
-- It echoes the filter_open arguments and upper-cases the body, which lets the
-- test confirm that arguments and content flow through the lua: filter path. It
-- is not a production filter. Runs on Lua 5.1 through 5.4 and LuaJIT.
