-/**
- * "struct strset" is a hashed string set: you can add strings to this
- * library, and it stores them as a set of unique strings.  You can
- * get the size of the set, and you can enumerate through all values.
- *
- * It is important to note that the strset does not copy the string
- * values - it stores the exact pointers it was given in strset_add().
