[erlang-questions] question about eldap and ssh

[Kenneth Lundin]

Just a clarification.

The dependency information given in the .app file is only intended to give
info about the start order dependency. I.e. that another application needs
to be started before this application is started.

Some applications are just libraries of code and does not have any
processes that need to be started. This is the case for public_key and asn1.

So you cannot rely on the info in the .app files when it comes to run-time
dependencys (you don't get the complete picture).
For getting the complete picture you can use reltool and or xref.

This is how it is today. It might be good to include a more complete
dependency info in the .app files but we are not there yet.
