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.
