following snippet which ends up being simpler than overwriting the wrap
phase.
The main parts added are the modules field and snippet field; I simply
added the whole source field so it is clear where those two fields go
within the package definition.

                 #t))))

After reinstalling onlykey-agent with the above change, I got the following
runtime error when running onlykey-gpg init "Firstname Lastname <
test@gmail.com>".

From what I can tell, the issue is that the inherited __str__ for Onlykey
class uses __name__ which resolves to '.onlykey-gpg'. This results in
trying to get the full path for
'.onlykey-gpg-gpg-agent' which doesn't exist. I think it should be instead
trying to get the path of 'onlykey-gpg-agent'. I plan on trying to patch
lib-agent to define a __str__ method that returns 'onlykey' for Onlykey
class.
I'm hoping that will fix the issue.

At the end of this, I plan to submit a bug report as you suggested.
