// The following code is taken from OpenBSD ar:
// http://www.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ar/
// It has been slightly modified:
// -return error codes instead exit() in functions
// -use the stdio file I/O functions instead the file descriptor based ones
// -merged into one cxx file
// -no additional options supported
// The coding style hasn't been modified.
