@cindex dates in archive
Preserve the @emph{original} dates of members when extracting them. If
you do not specify this modifier, files extracted from the archive
are stamped with the time of extraction.

+Use the full path name when matching names in the archive. @sc{gnu}
+@code{ar} can not create an archive with a full path name (such archives
+are not POSIX complaint), but other archive creators can. This option
+will cause @sc{gnu} @code{ar} to match file names using a complete path
+name, which can be convenient when extracting a single file from an
+archive created by another tool.

Display full contents of the current archive, in ``verbose'' style

enhancement, rather than present for MRI compatibility.)
