-This is c-ares, a forked version of the original ares. The original ares
-README follows below, the c-ares specific details are in README.cares
-
-====================================================================
-
-This is ares, an asynchronous resolver library. It is intended for
-applications which need to perform DNS queries without blocking, or
-need to perform multiple DNS queries in parallel. The primary
-examples of such applications are servers which communicate with
-multiple clients and programs with graphical user interfaces.
-
-This library implementation is not especially portable to crufty old
-systems like SunOS 4. It assumes a compiler which can handle ANSI C
-syntax, a system malloc which properly handles realloc(NULL, foo) and
-free(NULL), and a reasonably up-to-date <arpa/nameser.h>.
-
-I have attempted to preserve the externally visible behavior of the
-BIND resolver in nearly all respects. The API of the library is, of
-course, very different from the synchronous BIND API; instead of
-invoking a function like res_send() and getting a return value back
-indicating the number of bytes in the response, you invoke a function
-like ares_send() and give it a callback function to invoke when the
-response arrives. You then have to select() on the file descriptors
-indicated by ares_fds(), with a timeout given by ares_timeout(). You
-call ares_process() when select() returns.
-
-Some features are missing from the current version of ares, relative
-to the BIND resolver:
-
- * There is no IPV6 support. [not true for c-ares]
- * There is no hostname verification.
- * There is no logging of unexpected events.
- * There is no debugging-oriented logging.
- * There is no YP support.
-
-libares requires an ANSI compiler to compile and use. To build the
-library, just run "./configure" and "make". To install it, run "make
-install". Run "./configure --help" to see a list of options you can
-provide to configure to change how the library builds. libares has no
-data files, so you can move the include file and library around freely
-without leaving behind any dependencies on old paths. Building the
-library will also build the "adig" program, a little toy for trying
-out the library. It doesn't get installed.
-
-libares is distributed at athena-dist.mit.edu:pub/ATHENA/ares. Please
-send bug reports and comments to ghudson@mit.edu.
