+
+
+/*
+ * No matter what the operating system, this module must provide the
+ * following services to its callers.
+ *
+ * input_file_begin()			Call once before anything else.
+ *
+ * input_file_end()			Call once after everything else.
+ *
+ * input_file_buffer_size()		Call anytime. Returns largest possible
+ *					delivery from
+ *					input_file_give_next_buffer().
+ *
+ * input_file_open(name)		Call once for each input file.
+ *
+ * input_file_give_next_buffer(where)	Call once to get each new buffer.
+ *					Return 0: no more chars left in file,
+ *					   the file has already been closed.
+ *					Otherwise: return a pointer to just
+ *					   after the last character we read
+ *					   into the buffer.
+ *					If we can only read 0 characters, then
+ *					end-of-file is faked.
+ *
+ * input_file_push()			Push state, which can be restored
+ *					later.  Does implicit input_file_begin.
+ *					Returns char * to saved state.
+ *
+ * input_file_pop (arg)			Pops previously saved state.
+ *
+ * input_file_close ()			Closes opened file.
+ *
+ * All errors are reported (using as_perror) so caller doesn't have to think
+ * about I/O errors. No I/O errors are fatal: an end-of-file may be faked.
