# Included build file to build transducers for list-based spellers, ie spellers
# that either *is* a list (e.g. hunspell) or needs a generated list before
# further processing (Polderland/PLX spellers). The fst's produced here are
# common to both speller types, and further processing is done in separate
# subdirs & build files.

# Hfst fst variables:
GT_SPELLER_SRC_HFST=../generator-speller-gt-norm.hfst
GT_COMMON_LISTSPELLER_HFST=

# Xerox fst variables - Xerox can be used for building the list-based spellers:
GT_SPELLER_SRC_XFST=../analyser-speller-gt-norm.xfst
GT_COMMON_LISTSPELLER_XFST=
