+- *  USENIX conference", p. 27-42.
+- *
+- * It differs in a number of ways from the version described in the
+- * paper.  First of all, threads are not an issue during I/O and we
+- * also don't have to worry about having multiple regions, since
+- * fortran's I/O model only allows you to be one place at a time.
+- *
+- * On the other hand, we have to be able to writing at the end of a
+- * stream, read from the start of a stream or read and write blocks of
+- * bytes from an arbitrary position.  After opening a file, a pointer
+- * to a stream structure is returned, which is used to handle file
+- * accesses until the file is closed.
+- *
+- * salloc_at_r(stream, len, where)-- Given a stream pointer, return a
+- * pointer to a block of memory that mirror the file at position
+- * 'where' that is 'len' bytes long.  The len integer is updated to
+- * reflect how many bytes were actually read.  The only reason for a
+- * short read is end of file.  The file pointer is updated.  The
+- * pointer is valid until the next call to salloc_*.
+- *
+- * salloc_at_w(stream, len, where)-- Given the stream pointer, returns
+- * a pointer to a block of memory that is updated to reflect the state
+- * of the file.  The length of the buffer is always equal to that
+- * requested.  The buffer must be completely set by the caller.  When
+- * data has been written, the sfree() function must be called to
+- * indicate that the caller is done writing data to the buffer.  This
+- * may or may not cause a physical write.
+- *
+- * Short forms of these are salloc_r() and salloc_w() which drop the
+- * 'where' parameter and use the current file pointer. */
