- # AX_PROG_FIG2DEV
- #
- # DESCRIPTION
- #
- # If `fig2dev' is found, sets the output variable `FIG2DEV' to `fig2dev',
- # and `FIG2DEV_ESPLANG' to the graphics language which can be used to
- # produce Encapsulated PostScript. Older versions of `fig2dev' produce EPS
- # with `-Lps' and new versions with `-Leps', this macro finds out the
- # correct language option automatically.
