+* Missing things in binparser.[ch]
 
-  Also need to add error checking.
+	- it's inconvenient that you have to pass in both a parser _and_
+	  a record. The record should just contain a pointer to the parser
+
+	- the bin_parser_seek_record (..., 1); idiom is a little dubious
+
+	- maybe convert BIN_UINT32 => { BIN_UINT, 4 } 
+	  we already have the width in the struct.

+	  having big/little endian.
 
 * Rename stack_stash_foreach_by_address() to stack_stash_foreach_unique(),
   or maybe not ...

 * Don't look in $(libdir) for separate debug files (since $libdir is
   the libdir for sysprof, not a system wide libdir). Tim Rowley.
   Fix is probably to hardcode /usr/lib, and also look in $libdir.
