Babel documentation example does not work

[SleepyBrett]

I just learned about org-babel and was excited to see that orgextended has support. I grabbed your documentation (https://github.com/ihdavids/orgextended_docs/blob/master/babel.org) and started running.

I immediately face-planted.

New document, saved to a fail babel-test.org

I put this in the document as directed:

##+BEGIN_SRC python :var x=5
  print(str(x))
##+END_SRC

then I had to try to figure out how to run it, which is not in the documentation, and found Org Exec Source Block .. nothing happened. Opened the console. Realized that the double hashes at the beginings of those lines is in error and replaced it with:

#+BEGIN_SRC python :var x=5
  print(str(x))
#+END_SRC

when I try to run this I get:

Traceback (most recent call last):
