HelpText.AutoBuild fails on Linux

[aggieben]

Here's the output when I try to run my command with --help:

Exact same code and dnx version works fine on Windows desktop CLR.

Stack:
Mono 4.0.4 (Stable 4.0.4.1/5ab4c0d)
dnx 1.0.0-beta7 Mono/Linux/x64

#250 explains why I'm replying late...

Hi @aggieben, can I know what version of Command Line Parser are you using?

Thank you.

[aggieben]

Up to this point I have been using 2.0.273-beta.

There was an issue with --help, but it was recently fixed.

1. Can you post your Options class?

2. Have tried executing the same app on Windows?

P.S.: please try use sources from GitHub, latest is 2.0.275-beta; it's always a good idea build from sources: not all fixes make the version change (also if normally this happens).
