# At the current time (20080824) nesc will not build from a separate build
# directory.  At least two problems exist.  More may be present beyone these
# two:
#    1 - The include path when desiring to include libcpp/config.h includes
#        the @srcdir@/libcpp directory where config.in exists, but not the
#        @blddir@ (?) where config.h is actually generated.
#    2 - The java Makefiles assume that .java is in the same directory where
#        the .class is to be compiled and placed.
#
# For now, the solution is quite hackish: copy the source directory to the
# build directory before running configure.
