 ATLAS for Debian
-----------------------
+================
 
 Starting from Atlas 3.8.3-1, the whole build process has been rewritten.
 It is now using most of the debhelper tools and simplify the management of 
 other archs.

 Why optimized packages are no longer available?
-===============================================
+-----------------------------------------------
 
- Before version 3.8.3-25, optimized binary packages were provided.
- However, due to the fact that most Atlas optimisations are done at build time,
- it has been decided to remove them and give priority to locally built packages.

 Building Optimized Atlas Packages on your ARCH
-==============================================
+----------------------------------------------
 
 Building your own optimized packages of Atlas is straightforward.
-Just get the sources of the package:
+Just get the sources of the package and its build-dependencies:
 
 # apt-get source atlas
+# apt-get build-dep atlas
 
-and type
+and type the following from the atlas source subdir:
 
 # fakeroot debian/rules custom
 
 it should produce a package called:
-# ../libatlas3-base_*.deb
 
-which should be optimized for the architecture Atlas has been built on.
+ ../libatlas3-base_*.deb
 
-All dependencies can be installed with the following command:
-# apt-get install build-essential dpkg-dev cdbs devscripts gfortran \
- liblapack-dev liblapack-pic texlive-latex-base
-
-or 
-
-# apt-get build-dep atlas

-How to load optimized/custom atlas libraries
-============================================
-
-In the previous packages of Atlas, each packages was configured through
-/etc/ld.so.conf.d/.
-Since Atlas 3.8.3-1, this mechanism has been removed since it is forbidden
-by the Debian Policy.

-Please see the section:
-"How to switch between the BLAS/LAPACK implementation and ATLAS optimized version" 
+which is optimized for the architecture Atlas has been built on. Then install
+the package using "dpkg -i".

 Thanks to David Cournapeau for providing all the patches for the shared 
 libraries managements.
