@echo off
:: ScripTreeForest launcher (cell + ring shell)
:: Usage:
::   run_scriptreeforest.bat
::   run_scriptreeforest.bat path\to\layout.scriptreering
::   run_scriptreeforest.bat --register-autostart-user path\to\layout.scriptreering
::
:: Mirrors run_scriptree.bat's Python search logic so a portable
:: install works the same way for both the editor and the cell shell.
:: Microsoft Store python stubs are filtered out automatically (they
:: are 0-byte App Execution Aliases that open the Store and exit —
:: picking one would silently kill the launch with no visible error).
