If set to true (by default), variables read in from
|
|
<link linkend="config.files">config files</link> will overwrite each
|
|
other. Otherwise, the variables will be pushed onto an array. This is
|
|
helpful if you want to store arrays of data in config files, just list
|
|
each element multiple times.
