25 # appropriate flags to CFLAGS and export the link sequence to
26 # the variable XLIB.
27 # In your configure.in file add:
28 # LF_PATH_XLIB
29 # In your Makefile.am add

33 # Just added EMBOSS into LF_PATH_XLIB so that on the systems where
34 # LF_PATH_XLIB exists there are no duplication errors.
