/**

|
* This is similar to a ConfigVariableList, but it returns its list as a
|
||
|
|
* DSearchPath, as a list of directories.
|
||
|
|
*
|
||
|
|
* You may locally append directories to the end of the search path with the
|
||
|
|
* methods here, or prepend them to the beginning. Use these methods to make
|
||
|
|
* adjustments to the path; do not attempt to directly modify the const
|
||
|
|
* DSearchPath object returned by get_value().
|
||
|
|
*
|
||
|
|
* Unlike other ConfigVariable types, local changes (made by calling
|
||
|
|
* append_directory() and prepend_directory()) are specific to this particular
|
||
|
|
* instance of the ConfigVariableSearchPath. A separate instance of the same
|
||
|
|
* variable, created by using the same name to the constructor, will not
|
||
|
|
* reflect the local changes.
