+# - 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
+##########
+### List of vendors (BLA_VENDOR) valid in this module
+## Goto,ATLAS PhiPACK,CXML,DXML,SunPerf,SCSL,SGIMATH,IBMESSL,Intel10_32 (intel mkl v10 32 bit),Intel10_64lp (intel mkl v10 64 bit,lp thread model, lp64 model),
+## Intel10_64lp_seq (intel mkl v10 64 bit,sequential code, lp64 model),
+## Intel( older versions of mkl 32 and 64 bit), ACML,ACML_MP,ACML_GPU,Apple, NAS, Generic
+# C/CXX should be enabled to use Intel mkl
