+# Find BLAS library
+#
+# This module finds an installed fortran library that implements the
+# BLAS linear-algebra interface (see http://www.netlib.org/blas/).  The
+# list of libraries searched for is taken from the autoconf macro file,
+# acx_blas.m4 (distributed at
 # http://ac-archive.sourceforge.net/ac-archive/acx_blas.html).
 #
 # This module sets the following variables:
-#  BLAS_FOUND - set to true if a library implementing the BLAS interface
-#    is found
-#  BLAS_LINKER_FLAGS - uncached list of required linker flags (excluding -l
-#    and -L).
-#  BLAS_LIBRARIES - uncached list of libraries (using full path name) to
-#    link against to use BLAS
-#  BLAS95_LIBRARIES - uncached list of libraries (using full path name)
-#    to link against to use BLAS95 interface
-#  BLAS95_FOUND - set to true if a library implementing the BLAS f95 interface
-#    is found
-#  BLA_STATIC  if set on this determines what kind of linkage we do (static)
-#  BLA_VENDOR  if set checks only the specified vendor, if not set checks
-#     all the possibilities
-#  BLA_F95     if set on tries to find the f95 interfaces for BLAS/LAPACK
