"""Install psutil on Termux/Android by patching upstream platform detection.

psutil's setup currently gates Linux sources behind

``sys.platform.startswith('linux')``. On Termux, Python reports

``sys.platform == 'android'``, so ``pip install psutil`` aborts with

"platform android is not supported" — even though psutil compiles fine

when the Linux source path is reused.

This script downloads the official psutil sdist, applies a one-line

patch (``LINUX = sys.platform.startswith(("linux", "android"))``), and

installs the patched tree with ``pip install --no-build-isolation``.

Usage:

python scripts/install_psutil_android.py [--pip "/path/to/pip"] [--uv]

When neither flag is given, the script auto-detects ``uv`` on PATH and

falls back to ``<sys.executable> -m pip``.

This is a stopgap. Remove once psutil upstream merges

https://github.com/giampaolo/psutil/pull/2762 and ships a release.
