| r.db | Simple and performance-friendly relational database
+------+

The database of r.db is based on index tables of key-size depth.
The key is the index of the key-bucket array which opens the search
space to a single key.

Items are directly sorted

  [255] key buckets

 - Compiles simple SQL-like sentences into a set of r.db queries

void **iter = r_db_sql_query("select * from flags");
while(r_db_ptr(iter)) {
	struct foo_t *foo = r_db_ptr(iter);
	iter = r_db_ptr_next(iter);
