+- properly manage quotes in shlex
+X remove the _new() functions
+- iterate children nodes without chaining them
+- add a tk vector type: will be used in several nodes (ex: or, seq, ...)
+- check allocation model everywhere
+- checkpatch?
+- use linux style (update .emacs)
+- better logs
+- return values
+- use errno when returning pointers
+- missing static / const
+- license: "s/neither the name...may/the names of its contributors may not/"
+- check all completion nodes
+X split ecoli_tk.h
+- cache results when appropriate?
+- size_t or unsigned int?
+X rename:
+ X ec_tk -> ec_node
+ X ec_parsed_tk -> ec_parsed
+ X ec_completed_tk -> ec_completed
+ X tk, gen_tk, token, ... -> node
+ X tokens -> input_str / input_strvec ?
+- use is_err() or errno for funcs returning ptrs, or use errno for all funcs
+- save node path in completion to fix help string
+- code coverage
+- try to hide structures
+- anything better than weakref?
+- add get_max_parse_len() for all relevant nodes
+- add ec_node_defaults.[ch] providing usual implementations of node methods
+- use vec for strvec

+dependencies
+============
+
+X pass the current parsed state when parsing/completing
+X new node "once"
+- new node "condition"
+
+logs
+====
+
+- register log types
+
+yaml
+====
+
+X register nodes by name
+- interface to add attributes: all nodes must be configurable through a
+ generic api
+ - attr string
+ - attr string list
+ - attr node
+ - attr node list
+ - attr int
+
+- yaml interface to create nodes
