-        bool "ar"

-        help
-          ar is an archival utility program used to create, modify, and
-          extract contents from archives. An archive is a single file holding
-          a collection of other files in a structure that makes it possible to
-          retrieve the original individual files (called archive members).
-          The original files' contents, mode (permissions), timestamp, owner,
-          and group are preserved in the archive, and can be restored on
-          extraction.
-
-          The stored filename is limited to 15 characters. (for more information
-          see long filename support).
-          ar has 60 bytes of overheads for every stored file.
-
-          This implementation of ar can extract archives, it cannot create or
-          modify them.
-          On an x86 system, the ar applet adds about 1K.
