-- cheatengine-bin (Arch Linux): per-user script overlay.
--
-- Cheat Engine resolves its content directory from the executable's real
-- path (/proc/self/exe), so the packaged install under /usr/lib/cheatengine
-- must stay read-only and cannot be relocated with symlinks. The one hook CE
-- offers that follows the process working directory instead is main.lua:
-- a main.lua in the CWD is loaded in preference to the packaged one
-- (InitializeLuaScripts in LuaHandler.pas).
--
-- The /usr/bin/cheatengine launcher therefore starts CE with its CWD set to
-- a per-user directory (default ~/.local/share/cheatengine) where this file
-- is symlinked as main.lua, and passes NOAUTORUN so CE's own autorun scan is
-- skipped. This file restores stock startup, then re-runs the autorun scan
-- with user precedence:
--
-- * put your own scripts in <userdir>/autorun/NAME.lua
-- * a user script named like a packaged autorun script replaces it
-- * everything else keeps loading from /usr/lib/cheatengine/autorun
--
-- Like upstream, only files matching *.lua (lowercase, non-recursive) load.
local PKGDIR = '/usr/lib/cheatengine/'
local USER_AUTORUN = 'autorun/' -- relative to CWD = per-user directory
-- Stock bootstrap: packaged main.lua does require("defines"), which must
-- resolve against the package dir now that the CWD is the user dir.
