+  =========================
+  libr - codename 'radare2'
+  =========================
+
+LibR is the refactoring of the old radare1 core in a set of libraries
+defining the APIs of radare2.
+
+The library 'libr' is composed by different modules, each one implementing
+working modules of radare, so then, we get a complete set of libraries for
+analyzing code, disassembling bytes, dumping bytes, plugin handling, etc..
+
+The 'R' is for refactoring, reversing, radare, ...
+
+Each module has its own test directory (t/) which contains simple applications
+using the upper directory code and linking against the direct dependencies.
+
+This enables a fine-grained test level for checking all functionalities in
+one shot and give us the opportunity to write radare2 as test programs.

+----------------------------------------[ todo 
+
+|| asm || 
+---------
+  - Add support for more architectures
+  - Add lua disassembler
+  - Add java, dalvik, xtensa achiecture (mm cpu)
+  - http://git.linux-xtensa.org/cgi-bin/git.cgi?p=buildroot/buildroot-xtensa;a=blob;f=toolchain/binutils/binutils-xtensa_dc232b.tgz;h=214164399158c540a3033e52b3bb9f65c55289af;hb=HEAD
+  - Vala API should not use State
+  - Fix cpp issues
+  - Fix endianess issues
+
+|| anal ||  **MISSING**
+----------
+  - define api, write vapi, integrate in core, etc..
+
+|| bin || 
+---------
+  - No Vala api yet
+  - Add support for PE64, mach0 and java class
+  - Add dex format support (android)
+
+|| cmd ||
+---------
+  - long commands not yet tested at all
+  - added interface to export command list into an autocompletable
+    argc, argv for dietline
+
+|| line ||
+----------
+  - make it work with state like teh rest
+  - add support for readline callbacks
+
+|| config ||
+------------
+  - missing default callback for int assign
+
+|| cons ||
+----------
+  - add pipe_to_buffer..not only file descriptors
+  - major cleanup
+  - split in multiple files
+  - get_real_columns() should be renamed to get_columns()
+
+|| flags ||
+-----------
+  - Define a way to iterate flags from vala
+  - We probably need more methods
+
+|| hash ||
+----------
+  - Drop State() ?
+
+|| diff ||
+----------
+  - Needs to fix the delta diffing algorithm
+  - Reimplement delta diffing in C
+
+|| sign ||
+----------
+  - Define attributes and weights
+  - Decide collissions based on these patterns
+
+|| meta || **MISSING**
+----------
+
+|| lib ||
+---------
+  - Cleanup and test w32/osx support
+
+|| debug ||
+-----------
+  - define plugin extensions (use vm from here)
