4 This package is based on ares 1.1.1 (written by Greg Hudson). I decided to
5 fork and release a separate project since the ares author didn't want the
6 improvements that were vital for our use of it.
8 This package is dubbed 'c-ares' since I (Daniel Stenberg) wanted this for use
9 within the curl project (hence the letter C) and it makes a nice pun. Also,
10 c-ares is not API compatible with ares: a new name makes that more obvious to
13 The full source code is available in the 'c-ares' release archives, and in the
14 'ares' subdir of the curl CVS source repository.

28 NOTES FOR C-ARES HACKERS
30 The following notes apply to c-ares version 1.6.1 and later.
32 * The distributed ares_build.h file is only intended to be used on systems
33 which can not run the also distributed configure script.
35 * The distributed ares_build.h file is generated as a copy of ares_build.h.dist
36 when the c-ares source code distribution archive file is originally created.
38 * If you check out from CVS on a non-configure platform, you must run the
39 appropriate buildconf* script to set up ares_build.h and other local files
40 before being able of compiling the library.
42 * On systems capable of running the configure script, the configure process
43 will overwrite the distributed ares_build.h file with one that is suitable
44 and specific to the library being configured and built, this new file is
45 generated from the ares_build.h.in template file.
47 * If you intend to distribute an already compiled c-ares library you _MUST_
48 also distribute along with it the generated ares_build.h which has been
49 used to compile it. Otherwise the library will be of no use for the users of
50 the library that you have built. It is _your_ responsability to provide this
51 file. No one at the c-ares project can know how you have built the library.
53 * File ares_build.h includes platform and configuration dependant info,
54 and must not be modified by anyone. Configure script generates it for you.
56 * We cannot assume anything else but very basic compiler features being
57 present. While c-ares requires an ANSI C compiler to build, some of the
58 earlier ANSI compilers clearly can't deal with some preprocessor operators.
60 * Newlines must remain unix-style for older compilers' sake.
62 * Comments must be written in the old-style /* unnested C-fashion */
