+Bootstrap script is the fastest way to experiment with sunzi.  No external
+Python library is needed as Python side is well-managed in the isolated
+virtualenv environment.  This snippet will setup the environment in the
+current dir (but feel free to modify as per your needs)::

-    ENV=.
-    curl $URL | python -c 'import
sys;__file__="_";exec(sys.stdin.read())' $ENV

sys;__file__="_";exec(sys.stdin.read())' $ARGS

+before rerunning the application, etc.
