-B, --base-url [base] does not seem to do anything

[GieziJo]

I'm trying to make presskit understand that it should link to my projects in base/project and not /project.
As far as I understood, adding -B base to the build command should take care of this, but it doesn't seem to be doing anything.

from presskit-build.js:

'prefix absolute urls with [base] (if your presskit is not at the root of your server)'

Am I doing something wrong or did I misunderstand the command?

P.S. thanks a lot for the awesome project and work!
