# Unless --with-botan-config is given, we first try to find these config

# a compilation test (ACX_TRY_BOTAN_TOOL). If none are found, or none of
# them work, we see if pkg-config is available. If so, we try the several
# potential pkg-config .pc files. Again, on some systems, these can return
# incorrect information as well, so the try-compile test is repeated for
# each.
#
# If a working config script or pkgconfig file is found, we then munge its
# output for use in our Makefiles, and to make sure it works, another header
# and compilation test is done (this should also check whether we can compile
# against botan should neither -config scripts nor pkgconfig data exist).
