33 ar is an archival utility program used to create, modify, and
34 extract contents from archives. In practice, it is used exclusively
35 for object module archives used by compilers.
37 On an x86 system, the ar applet adds about 1K.
39 Unless you have a specific application which requires ar, you should
40 probably say N here: most compilers come with their own ar utility.
