CouchDB reads files from the following locations, in the following order.
PREFIX/default.ini
PREFIX/default.d/*
PREFIX/local.ini
PREFIX/local.d/*
Settings in successive documents override the settings in earlier
entries. For example, setting the bind_address
parameter in local.ini would override any
setting in default.ini.
The default.ini file may be overwritten
during an upgrade or re-installation, so localised changes
should be made to the local.ini file or
files within the local.d directory.
