* Input (choose one of these):
*
* SORT_INPUT_FILE file of a given name
- * SORT_INPUT_FB fastbuf stream
+ * SORT_INPUT_FB seekable fastbuf stream
+ * SORT_INPUT_PIPE non-seekable fastbuf stream
* SORT_INPUT_PRESORT custom presorter. Calls function
* int PREFIX_presort(struct fastbuf *dest, void *buf, size_t bufsize);
* to get successive batches of pre-sorted data.
*
* SORT_UNIQUE all items have distinct keys (checked in debug mode)
*
- * FIXME: Maybe implement these:
- * ??? SORT_DELETE_INPUT a C expression, if true, the input files are
- * deleted as soon as possible
- * ??? SORT_ALIGNED
- *
* The function generated:
*
* <outfb> PREFIX_SORT(<in>, <out> [,<range>]), where:
