Corrections and Updates
Corrections to these documents can be submitted as patch files to the EPICS core
developers, or as merge requests or pull requests to the 7.0 branch of Base.
The document sources can be found in the modules/database/src/std/rec and
modules/database/src/ioc/db directories in files with extension .dbd.pod.
The documentation source format is a combination of the EPICS DBD file format
with an extended version of Perl's POD (plain old documentation); run perldoc pod for details of POD.
