# Usage:
#
# NEON_LIBRARY
# or NEON_BUNDLED(srcdir, [ACTIONS-IF-BUNDLED], [ACTIONS-IF-NOT_BUNDLED])
# or NEON_VPATH_BUNDLED(srcdir, builddir,
# [ACTIONS-IF-BUNDLED], [ACTIONS-IF-NOT-BUNDLED])
#
# where srcdir is the location of bundled neon 'src' directory.
# If using a VPATH-enabled build, builddir is the location of the
# build directory corresponding to srcdir.
#
# If a bundled build *is* being used, ACTIONS-IF-BUNDLED will be
# evaluated. These actions should ensure that 'make' is run
# in srcdir, and that one of NEON_NORMAL_BUILD or NEON_LIBTOOL_BUILD
# is called.
#
# After calling one of the above macros, if the NEON_NEED_XML_PARSER
# variable is set to "yes", then you must configure an XML parser
# too. You can do this your own way, or do it easily using the
# NEON_XML_PARSER() macro. Example usage for where we have bundled the
# neon sources in a directory called libneon, and bundled expat
# sources in a directory called 'expat'.
#
# NEON_BUNDLED(libneon, [
# NEON_XML_PARSER(expat)
# NEON_NORMAL_BUILD
# ])
#
# Alternatively, for a simple standalone app with neon as a
# dependancy, use just:
#
# NEON_LIBRARY
#
# and rely on the user installing neon correctly.
#
# You are free to configure an XML parser any other way you like,
# but the end result must be, either expat or libxml will get linked
# in, and HAVE_EXPAT or HAVE_LIBXML is defined appropriately.
#
# To set up the bundled build environment, call
#
# NEON_NORMAL_BUILD
# or
# NEON_LIBTOOL_BUILD
#
# depending on whether you are using libtool to build, or not.
# Both these macros take an optional argument specifying the set
# of object files you wish to build: if the argument is not given,
# all of neon will be built.
