The gnu program creates, modifies, and extracts from archives. An archive is a single file holding
ar
a collection of other files in a structure that makes it possible to retrieve the original individual files
(called members of the archive).
The original files' contents, mode (permissions), timestamp, owner, and group are preserved in the
archive, and can be restored on extraction.
gnu can maintain archives whose members have names of any length; however, depending on how
ar
is configured on your system, a limit on member-name length may be imposed for compatibility
ar
with archive formats maintained with other tools. If it exists, the limit is often 15 characters (typical
of formats related to a.out) or 16 characters (typical of formats related to coff).
