/* This package provides input and output routines for lists of
   integers.  For both input and output, lists are represented as
   sequences of integers within angle brackets (e.g. <1 2 3>).

   Read_int_list takes a FILE * as its argument and reads one list
   from that stream.  If a legal list specification is not found,
   read_int_list prints an error message and returns as much of the
   list as it was successfully able to read.  This means that if the
   first (non-whitespace) character read is not '<', the_empty_list
   will be returned AND NO INPUT WILL BE CONSUMED.  Thus, if another
   attempt is immediately made to read a list, the same error will
   occur.

   Print_int_list takes a FILE * and a list as its arguments, and
   prints the list to the given stream using angle bracket notation.
   No carriage return is printed.

   To use the package, you will need to follow the instructions in
   the file "lists.h", taking care to typedef list_item_type to be
   int.  Then, include "list-io.h" after your inclusion of "lists.h":

       typedef int list_item_type;
       #include "lists.h"
       #include "list-io.h"
