Removed -tt from shebang lines because GNU env can't handle it and the test suite now checks for tabs. 12 years ago			`#!/usr/bin/env python3`
Started work on main runner file. 12 years ago
Moved scripts in the module and started work to run them via the main meson command. 9 years ago			`# Copyright 2016 The Meson development team`

Renamed meson package to mesonbuild so that we can have a script named meson in the same toplevel dir. 9 years ago			`from mesonbuild import mesonmain`
Moved scripts in the module and started work to run them via the main meson command. 9 years ago			`import sys, os`

User argv[0] to internally relaunch meson.py When installing Meson distutils may choose to put shim scripts in the PATH that only set up the egg requirements before launching the real `meson.py` contained in the egg. This means that __file__ points to the real `meson.py` file, but launching it directly is doomed to fail as it's missing the metadata contained in the shim to set up the path egg, resulting in errors when trying to import the `mesonbuild` module. A similar issue affects Meson when installed as a zipapp, with the current code going great lengths to figure out how to relaunch itself. Using argv[0] avoids these issues as it gives us the way the current executable has been launched, so we are pretty much guaranteed that using it will create another instance of the same executable. 8 years ago			`sys.exit(mesonmain.run(sys.argv[0], sys.argv[1:]))`
