+# this is a smoke-test using "./bin/tahoe" to:
+#
+# 1. create an introducer
+# 2. create 5 storage nodes
+# 3. create 2 client nodes (client0 = alice, client1 = bob)
+# 4. Alice creates a magic-folder ("magik:")
+# 5. Alice invites Bob
+# 6. Bob joins
+#
+# After that, some basic tests are performed; see the "if True:"
+# blocks to turn some on or off. Could benefit from some cleanups
+# etc. but this seems useful out of the gate for quick testing.
+#
+# TO RUN:
+# from top-level of your checkout (we use "./bin/tahoe"):
+# python src/allmydata/test/check_magicfolder_smoke.py
+#
+# This will create "./smoke_magicfolder" (which is disposable) and
+# contains all the Tahoe basedirs for the introducer, storage nodes,
+# clients, and the clients' magic-folders. NOTE that if these
+# directories already exist they will NOT be re-created. So kill the
+# grid and then "rm -rf smoke_magicfolder" if you want to re-run the
+# tests cleanly.
+#
+# Run the script with a single arg, "kill" to run "tahoe stop" on all
+# the nodes.
+#
+# This will have "tahoe start" -ed all the nodes, so you can continue
+# to play around after the script exits.
