[Doc] .vagrantplugins documentation missing

[gimler]

Where can i find the documentation for the .vagrantplugins file?

Hi,

We've chosen not to document this because it isn't a feature we want to officially support. We are supporting it for backwards compatibility reasons for folks that were putting plugins in their Vagrantfile. But we're pretending it doesn't exist.

@mitchellh Sorry to chime in on an old closed issue: But do you have any pointer to the doc in regards to what should be used instead? I failed to come up with something similar.

Our use case is here that we do have some project specific commands (stuff like vagrant logs tail to tail the random logfiles a specific application has and other app-specific tedious tasks we would like to make available to developers outside the vagrantbox).
