317	Structured binary data editor	Jiri Svoboda		"As suggested by Martin Sucha, it would be useful to have a tool to view and edit structured binary data, such as program memory structures (task memory, core file), file system structures, etc.

I would suggest to create a library that would:
 * define data structures (and API to manipulate them) to describe types (basic types, arrays, structs, unions)
 * enumerate fields
 * compute field offset (address)
 * read and write fields
 * convert between binary and textual representation
 * find targets of links

The type definitions would be defined by plugins:
 * plugin for reading DWARF data
 * plugin for reading textual definitions
 * plugin for specific set of types (e.g. ext2)

as well as definitions of other link types than pointer (e.g. block address).

Also plugins for different memory back-ends can be provided (possibly by the user):
 * (core) file
 * task memory (via Udebug)
 * block device

On top of this library we can provide tools such as an interactive or command-based browser/editor. It could be also used as part of a debugger and possibly for other debugging purposes.
