+This directory contains the sources and tools necessary for building mandatory
+dependencies of numpy/lapack, with a special focus on Windows.
+
+The directory is organized as followed:
+        * src: sources of the dependencies
+        * tools: various scripts to build the binaries of the dependencies
+
+In Particular, the tools directory contains:
+        * a build.py script to build blas/lapack on Win32 from a configuration
+        file.
+        * basic.nsi: a NSIS script to build an installer for blas/lapack under
+        different architectures.
+
+The build.py tool
+=================
+
+dependencies:
+-------------
+
+cygwin with make, gcc, g77 and python
+
+How to use:
+-----------
+
+python tools/build.py tools/sse3.cfg
+
+Will build a blas/lapack using configuration in tools/sse3.cfg. In particular,
+it contains informations on whether to build atlas or not, which fortran
+compiler to use, etc...
+
+The basic.nsi script
+====================
+
+You need NSIS to use it: http://nsis.sourceforge.net/Main_Page You also need a
+small plugin cpu_caps, to tell NSIS wether the running CPU supports SSE2,
+SSE3, etc...
+
+It will look for binaries in the binaries directory: one directory per arch. A
+subdir mingw32 is used for differentiatin with the not-yet supported Win64.
