# library paths for libparted
# written by Damien Genet <damien.genet@free.fr>
dnl Usage:
dnl PARTED_CHECK_LIBPARTED([MINIMUM-VERSION, [ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]]])
dnl where MINIMUM-VERSION must be >= 1.2.8 and != 1.3.0
dnl
dnl Example:
dnl PARTED_CHECK_LIBPARTED(1.2.8, , [AC_MSG_ERROR([*** libparted >= 1.2.8 not installed - please install first ***])])

dnl Adds the required libraries to $PARTED_LIBS and does an
