IO CLASSES

The most commonly used IO class in Sather is OUT, as seen in the
hello world program:

    #OUT + "Hello world.\n";

ERR works the same as OUT except output goes to standard error.

IN provides methods for getting input from standard in.  If you
are looking for exotic ways to parse input, take a look at
STR_CURSOR in Strings.  Instead of providing lots of ways to
read in different kinds of values, the Sather idiom is to read
in the whole file in one gulp into memory and parse it there as
a string.  For most purposes this works well.

FILE can be used to access files in a Unixish way.  BFILE is an
equivalent for binary files (the difference shows up in portability
issues.)  Both of these will probably be replaced by a more general
and portable file/directory mechanism in the future.
