AC_INIT(wireshark, 1.9.0, http://bugs.wireshark.org/, , http://www.wireshark.org/)

dnl Check for CPU / vendor / OS
dnl The user is encouraged to use either `AC_CANONICAL_BUILD', or
dnl `AC_CANONICAL_HOST', or `AC_CANONICAL_TARGET', depending on the
dnl needs.  Using `AC_CANONICAL_TARGET' is enough to run the two other
dnl macros.
dnl
dnl As nothing in the Wireshark is itself a build tool (we are not,
dnl for example, a compiler that generates machine code), we probably
dnl don't need AC_CANONICAL_TARGET, so, in theory, we should be able
dnl to use AC_CANONICAL_BUILD and AC_CANONICAL_HOST - or perhaps just
dnl AC_CANONICAL_HOST - instead.  Note that we do have tools, such as
dnl lemon, that need to be built for the build machine, not for the
dnl host machine, so we might need both.
dnl
dnl This has to be done *after* AC_INIT, otherwise autogen.sh fails.

# XXX - should autogen.sh check for YACC/Bison and Flex?  A user building
# from a distribution tarball shouldn't have to have YACC/Bison or Flex,

# files and running Flex on .l files, but a user building from SVN
# will have to run YACC/Bison and Flex to process those files.
#
# On the other hand, what about users who use a distribution tarball to
# do development?  They *shouldn't* - that's what the SVN repository is
