+YOML - a DOM-like interface to YAML
+====
+
+YOML is a DOM-like interface to YAML, implemented as a wrapper around [libyaml](http://pyyaml.org/wiki/LibYAML).
+
+It is a header-only library. Just include the .h files to use the library.
+
+```
+#include "yoml.h" /* defines the structures */
+#include "yoml-parser.h" /* defines the parser */
+
+static yoml_t *parse_file(FILE *fp)
+{

+ yoml_t *doc;
+
+ yaml_parser_initialize(&parser);
+ yaml_parser_set_input_file(&parser, fp);
+
+ doc = yoml_parse_document(&parser, NULL);
+
+ yaml_parser_delete(&parser);
+
+ return doc;
+}
+
+static void dump_node(yoml_t *node, int indent)
+{
+ size_t i;
+
+ switch (node->type) {
+ case YOML_TYPE_SCALAR:
+ printf("%*s[SCALAR] %s\n", indent, "", node->data.scalar);
