33 | bool "ar" |
34 | default n |
35 | help |
36 | ar is an archival utility program used to create, modify, and |
37 | extract contents from archives. An archive is a single file holding |
38 | a collection of other files in a structure that makes it possible to |
39 | retrieve the original individual files (called archive members). |
40 | The original files' contents, mode (permissions), timestamp, owner, |
41 | and group are preserved in the archive, and can be restored on |
42 | extraction. |
43 | |
44 | The stored filename is limited to 15 characters. (for more information |
45 | see long filename support). |
46 | ar has 60 bytes of overheads for every stored file. |
47 | |
48 | This implementation of ar can extract archives, it cannot create or |
49 | modify them. |
50 | On an x86 system, the ar applet adds about 1K. |

59 | help |
60 | By default the ar format can only store the first 15 characters |
61 | of the filename, this option removes that limitation. |
62 | It supports the GNU ar long filename method which moves multiple long |
63 | filenames into a the data section of a new ar entry. |
