  36. help
  37. ar is an archival utility program used to create, modify, and
  38. extract contents from archives. An archive is a single file holding
  39. a collection of other files in a structure that makes it possible to
  40. retrieve the original individual files (called archive members).
  41. The original files' contents, mode (permissions), timestamp, owner,
  42. and group are preserved in the archive, and can be restored on
  43. extraction.
  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. This implementation of ar can extract archives, it cannot create or
  48. modify them.
  49. On an x86 system, the ar applet adds about 1K.
