wxSmith licensing term

[rts2003]

I need help clarifying the terms of wxSmith license.  The statement I found in this link is rather ambiguous.  Another post found around here states that I do not have to disclose the source code if I use wxSmith to develop my application.  The statement is also rather ambiguous:

You may not need to redistribute any of your code iff you don't use any portion of the code of wxSmith/C::B.

I am using swSmith to make an application.  Does that constitute "us[ing] the code of wxSmith/C::B"?  What kind of license is wxSmith under, and what terms allow the non-disclosure of the source code?  I want to have it clarified beyond any doubt.

"using the code" is more about including the functionality in your own application, e.g., if you copy-paste the sourcecode of wxSmith into your own application
