   9 # Shell script to build shared library versions of the modules; the
  10 # idea is to build an export list containing only the init*() function
  11 # for the module.  We _could_ assume for foomodule.o it was initfoo, but
  12 # that's asking for trouble... this is a little less efficient but correct.
  13 #
  14 # This is called by the Modules/Makefile as $(LDSHARED):
  15 #
  16 # $(LDSHARED) foomodule.o -o foomodule$(SO)
  17 #
  18 # Could also be called as:
  19 #
  20 # $(LDSHARED)  readline.o  -L/boot/home/config/lib -lreadline -ltermcap \
  21 # -o readline$(SO)
