# APPDIR should be the directory of the application that needs to be
# analysed.  It must contain a Makefile with the target '$1'.

# APPDIR_OBJS should be a list of objects files, in which the undefined
# references can be found.  Any 'undefined reference' for either a
# template function or template class that is occurs during linking
# causes an template instantiation to be added to the file <name>.tig
# where <name> is the first part of the object file <name>.o with the
# most undefined references in it.  If the file <name>.cc does not
# contain a line "#include "<name>.tig", then this line is added at
# the bottom of that file.
