							  DEFINITIONS IN THIS FILE

Symbols:

Z_WRITE, Z_READ, and Z_RDWR are the parameters to supply to zooopen()
and to open an existing file for write, read, and read-write
respectively.	Z_NEW is the parameter to supply to zoocreate() to
open an existing file or create a new file for write and read.  The
file must be opened in binary format, with no newline translation of
any kind.

Macros or functions:

zgetc(x) reads a character from ZOOFILE x.
zputc(c, f) writes a character to a ZOOFILE x.
zputchar(c) writes a character c to standard output.
MKDIR(x) creates a directory x.
