o finish/fix implementation of cfg_node_select()
o implement cfg_node_find()
- o fix internal linkage with "left sibling" pointer
o support for prefixes of all non-static symbols to better support embedding
o finish cfg.pod manual page (function description!)
o add ts-based test suite
+ o cleanup: token vs. option/argument nomenclature
+
+ CANDO
+
+ o Problem: \x00 oder \x{00} results in NUL-terminator, so better use ptr+len instead?
+ o optimize internal linkage with an additional "left sibling" pointer?
o add line tracking support
o add pre-processor with at least includes
- o add config tree verification!
+ o add config tree syntax verification!
o cfg.tok: in scanner: use an combination of dynamic buffer and atomic
symbol/token sub-library to allow first tokens of mostly arbitrary
size and then to store the tokens redundancy-free.
- o named parameters [--]name=value (options)
-- token vs. argument nomenclature
-- arguments/options vs. just token
