Usage: ./configure [options]

Options:
  --prefix=PREFIX   install files in PREFIX                          (1)
  --libdir=LIBDIR   install library files into LIBDIR                (2)
  --enable-fftw     enable FFTW library                              (+)
  --disable-fftw    disable FFTW library
  --enable-blas     enable BLAS library (ATLAS disabled)             (+)
  --disable-blas    disable BLAS library
  --enable-lapack   enable LAPACK library                            (+)
  --disable-lapack  disable LAPACK library
  --enable-cblas    enable CBLAS library (ATLAS disabled)            (+)
  --disable-cblas   disable CBLAS library
  --enable-atlas    enable ATLAS library (BLAS/CBLAS disabled)
  --disable-atlas   disable ATLAS library
  --enable-shared   build shared libraries if possible               (+)
  --disable-shared  do not build shared libraries
  --help            display this help end exit

(1) Absolute path has to be used. PREFIX=/usr/local by default.
(2) LIBDIR=PREFIX/lib by default
(+) option set by default

Note: ATLAS configuration procedure is interactive and asks a set of questions.
