Each gnats database located on a server has its own directory, as
listed in the databases (see The databases file and given when the mkdb utility is invoked
to initialize the database (see Initializing a new database).
This directory has several subdirectories, one of which is named
gnats-adm. This directory contains all configuration files
related to this specific database, including the categories,
submitters, responsible, states, classes,
dbconfig, addresses, states and
gnatsd.user_access, as well as two
files generated and maintained by gnats, index and
current.
