-OPERATIONS:
-  d - delete [files] from the archive
-  m - move [files] in the archive
-  p - print [files] found in the archive
-  q - quick append [files] to the archive
-  r - replace or insert [files] into the archive
-  s - act as ranlib
-  t - display contents of archive
-  x - extract [files] from the archive
-
-MODIFIERS:
-  [a] - put [files] after [relpos]
-  [b] - put [files] before [relpos] (same as [i])
-  [c] - do not warn if archive had to be created
-  [D] - use zero for timestamps and uids/gids (default)
-  [i] - put [files] before [relpos] (same as [b])
-  [l] - ignored for compatibility
-  [L] - add archive's contents
-  [o] - preserve original dates
-  [s] - create an archive index (cf. ranlib)
-  [S] - do not build a symbol table
-  [T] - create a thin archive
-  [u] - update only [files] newer than archive contents
-  [U] - use actual timestamps and uids/gids
-  [v] - be verbose about actions taken
