-A small and lightweight library that implements easy to use asynchronous
-wrappers around the libc NSS functions getaddrinfo(), res_query() and related.
+A C library for executing name service queries asynchronously. It is
+an asynchronous wrapper around getaddrinfo(3), getnameinfo(3),
+res_query(3) and res_search(3) from libc and libresolv.
+
+In contrast to GNU's asynchronous name resolving API,
+getaddrinfo_a(), libasyncns does not make use of UNIX signals for
+reporting completion of name queries. Instead, the API exports a
+standard UNIX file descriptor which may be integerated into custom
+main loops.
