41 default BUSYBOX_DEFAULT_AR # needs to be improved to be able to replace binutils ar
43 ar is an archival utility program used to create, modify, and
44 extract contents from archives. In practice, it is used exclusively
45 for object module archives used by compilers.
47 On an x86 system, the ar applet adds about 1K.
49 Unless you have a specific application which requires ar, you should
50 probably say N here: most compilers come with their own ar utility.

57 By default the ar format can only store the first 15 characters
58 of the filename, this option removes that limitation.
59 It supports the GNU ar long filename method which moves multiple long
60 filenames into a the data section of a new ar entry.
62 config BUSYBOX_CONFIG_FEATURE_AR_CREATE
63 bool "Support archive creation"
64 default BUSYBOX_DEFAULT_FEATURE_AR_CREATE
