help
ar is an archival utility program used to create, modify, and
extract contents from archives. In practice, it is used exclusively
for object module archives used by compilers.
- On an x86 system, the ar applet adds about 1K.
-
Unless you have a specific application which requires ar, you should
probably say N here: most compilers come with their own ar utility.
help
This enables archive creation (-c and -r) with busybox ar.
