I'm talking about a recursive function. I'm not sure what you mean by
recursive scripting.

Note that the current Make file already has recursion,

# Recursively scan the metafont .mf file $(1) for "input X;"
# and return all dependencies.
scan-mf = \
$(foreach f, $(shell test -f $(1) && sed -ne
"/^[[:space:]]*input[[:space:]]/s/^[[:space:]]*input\([^.;]*\)\(.mf;\|;\)/\1.mf/p"
$(1)), \
       $(call find-mf,$(f)) \
      $(call scan-mf,$(call find-mf,$(f))) \
)
