So I wanted to replace that functionality with Michael Davidsaver's dbdlint script.  So I got the code from github but I'm not able to communicate to the script my database definition.

The python exception being shown below is actually a symptom this error.
I've pushed some updates which change this to:

> ERROR   ../epics/base-git/dbd/base.dbd:5 incomplete-dbd - This tool must be run on an expanded .dbd.  (eg. softIoc.dbd, not base.dbd)

which I hope should be clearer.  dbdlint in full '-F' mode is meant to be run against an already
expanded .dbd file, such as would be loaded by an IOC.

I've also added a new warning -Wrec-append which which you may need to disable.
It trips when a record() appears a second time unless the recordtype is "*".
This was a Base 3.16 addition.

eg. "dbdlint -F -Wall -Wno-rec-append ...'


dbdlint also works with python3 now.
