Allows the entitlements-inherit option of electron-osx-sign to be passed.

Thanks for the contribution! Could you please add an entry to usage.txt?

[mcfedr]

I didn't re-indent the whole file right away, it pushes everything very far to the right, what do you think @malept ?

[malept]

Hmm. Try moving the description to the next line.

Also, un-capitalize "The", it's inconsistent with the rest of the argument descriptions.

[mcfedr]

ah, I even looked at the capitals and thought it should be small.

This is a more accurate link: https://www.npmjs.com/package/electron-osx-sign#opts

Also, you should add the same caveat as sign-entitlements:

(Currently limited to Mac App Store distribution.)

@malept The signing with entitlements should now work fine with darwin builds in the latest electron-osx-sign v0.3.0.

[malept]

@sethlu thanks for the correction. I guess the caveat needs to be removed from the entitlements docs, then. That can happen outside of this PR.

[sethlu]

@malept That may be better I think.
I'll find a way to explain the entitlements for darwin builds as they, apart from sandboxing an app, do not actually do much except interacting with iCloud services, iAP or things like that. It's pretty hard to access some of these Apple services with current builds of Electron, so basically entitlements could be ignored for darwin. The default entitlements for darwin is blank: If a darwin build is sandboxed, it should not also really function properly in the presence of frameworks like Squirrel.framework.

[malept]

Looks good. Squash the commits and I'll merge.

@malept squashed
