//config:   help

//config:     ar is an archival utility program used to create, modify, and

//config:     extract contents from archives. In practice, it is used exclusively

//config:     for object module archives used by compilers.

//config:

//config:     On an x86 system, the ar applet adds about 1K.

//config:

//config:     Unless you have a specific application which requires ar, you should

//config:     probably say N here: most compilers come with their own ar utility.

//config:

//config:config FEATURE_AR_LONG_FILENAMES

//config:   bool "Support for long filenames (not needed for debs)"

//config:   default y

//config:   depends on AR

//config:   help

//config:     By default the ar format can only store the first 15 characters

//config:     of the filename, this option removes that limitation.

//config:     It supports the GNU ar long filename method which moves multiple long

//config:     filenames into a the data section of a new ar entry.

//config:

//config:config FEATURE_AR_CREATE

//config:   bool "Support archive creation"

//config:   default y

//config:   depends on AR

//config:   help

//config:     This enables archive creation (-c and -r) with busybox ar.
