44    help
45      ar is an archival utility program used to create, modify, and
46      extract contents from archives. An archive is a single file holding
47      a collection of other files in a structure that makes it possible to
48      retrieve the original individual files (called archive members).
49      The original files' contents, mode (permissions), timestamp, owner,
50      and group are preserved in the archive, and can be restored on
51      extraction.
52
53      The stored filename is limited to 15 characters. (for more information
54      see long filename support).
55      ar has 60 bytes of overheads for every stored file.
56
57      This implementation of ar can extract archives, it cannot create or
58      modify them.
59      On an x86 system, the ar applet adds about 1K.
