Another problem is here when I ran a README.md by present:

> present README.md            

Traceback (most recent call last):
  File "/usr/local/lib/python3.6/dist-packages/present/markdown.py", line 242, in parse
    Element = eval(element_name)
  File "<string>", line 1, in <module>
NameError: name 'Strong' is not defined

During handling of the above exception, another exception occurred:

    sys.exit(cli())

@mitchgillin Thanks for reporting this! Looks like italics support varies on different shells, I'll look into this.

@agn-7 It should work for you if you're on Python 3.7+ and have present 0.5.0.

[vinayak-mehta]

This should be fixed with present v0.5.1, please reopen it if you still face the issue.

[mitchgillin]

Fixed for me! Thanks; can't wait to use it!
