CFCopySearchPathForDirectoriesInDomains returns the various
standard system directories where apps, resources, etc get
installed. Because queries can return multiple directories,
you get back a CFArray (which you should free when done) of
CFStrings. The directories are returned in search path order;
that is, the first place to look is returned first. This API
may return directories that do not exist yet. If NSUserDomain
is included in a query, then the results will contain "~" to
refer to the user's directory. Specify expandTilde to expand
this to the current user's home. Some calls might return no
??? On MacOS 8 this function currently returns an empty array.
