[+NAME?'"${.sh.file##*/}"' - unconfigures an OpenDJ instance]
[+DESCRIPTION?A convinience script to disable the related OpenDJ service instance and remove its configuration file from the related instance data directory. Use option \b-r\b to remove the related instance data directory completely (and thus \ball\b data stored in the instance!). However, re-using a data instance directory from an unconfigured instance is not supported and may result in an unexpected behavior!]
[H:help?Display this usage information and exit.]
[V:version?Display directory server version information and exit.]
[r:realclean?Forcibly remove the \bentire\b data directory of the related OpenDJ instance, no matter whether it is still in use.]
[+EXAMPLES]{
    [+Example 1?The following example unconfigures the default OpenDJ instance:]
    [+?$ SMF_FMRI=opendj25:test pfexec ./unconfigure -r]
	[+Example 2?Check the service config properties:]
	[+?$ svcprop -p config network/ldap/opendj25:test]
	[+Example 3?Remove the OpenDJ service instance "test" from the system:] 
	[+?# svccfg -s network/ldap/opendj25 "delete test"]
	[+?# svccfg -s network/ldap/opendj25 refresh]
}
[+ENVIRONMENTAL VARIABLES]{
    [+SMF_FMRI?The service instance to use. If unset or empty, \bnetwork/ldap/opendj25:default\b will be used.]
    [+FNTRACE?A comma or whitespace separated list of script function names to trace during their execution.]
}
[+SEE ALSO]{
