+#
+# This is a smoke test of bcachefs-tools.
+#
+# It builds the source with multiple options (debug, release, valgrind, FUSE)
+# and runs the test suite.
+#
+# Returns 0 on success, nonzero on any failure.
+#
+# Dependencies:
+#
+# valgrind, python3-pytest, python3-pytest-xdist
+#
+# On debian/ubuntu based systems, install with:
+#
+#   apt install valgrind python3-pytest python3-pytest-xdist
+#
+# You also currently need fuse 3.7 or later.  Fuse 3.7 unfortunately requires
+# debian sid or bullseye at this time, so you may need to install from source.
