+"""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.
