dnl Michele Martone's proposal for a transition towards the GNU build system for the PSBLAS library
dnl
dnl Process this file with autoconf to produce a configure script.
dnl
dnl usage : aclocal -I config/ && autoconf && ./configure && make
dnl then : VAR=VAL ./configure
dnl In some configurations (AIX) the next line is needed:
dnl MPIFC=mpxlf95 ./configure
dnl then : ./configure VAR=VAL
dnl then : ./configure --help=short
dnl then : ./configure --help
dnl the PSBLAS modules get this task difficult to accomplish!
dnl SEE : --module-path --include-path
dnl NOTE : There is no cross compilation support.
dnl NOTE : missing ifort and kl* library handling..
dnl NOTE : odd configurations like ifc + gcc still await in the mist of the unknown
