+This directory contains links to the Eigen library which is required
+to use the USER-SMD package in a LAMMPS input script.
+
+The Eigen library is available at http://eigen.tuxfamily.org.  It's
+a general C++ template library for linear algebra.
+
+You must perform the following steps yourself, or you can use the
+install.py Python script to automate any or all steps of the process.
+Type "python install.py" for instructions.
+
+1.  Download the Eigen tarball at http://eigen.tuxfamily.org and
+    unpack the tarball either in this /lib/smd directory or somewhere
+    else on your system.  It should unpack with into a directory with
+    a name similar to eigen-eigen-bdd17ee3b1b3.  Note that Eigen is a
+    template library, so you do not have to build it.
+
+2.  Create two soft links in this dir (lib/smd)
+    to the eigen directory.  E.g if you unpacked Eigen in this dir:
+      % ln -s eigen-eigen-bdd17ee3b1b3 includelink
+      % ln -s eigen-eigen-bdd17ee3b1b3 liblink
+    If you unpackaged Eigen somewhere else and renamed
+    the directory to just eigen, then do something like this:
+      % ln -s /home/sjplimp/tools/eigen includelink
+      % ln -s /home/sjplimp/tools/eigen liblink
+
+When these steps are complete you can build LAMMPS
+with the USER-SMD package installed:
+
+% cd lammps/src
+% make yes-user-smd
+% make g++ (or whatever target you wish)
+
+Note that if you download and unpack a new LAMMPS tarball, the
+"includelink" and "liblink" files will be lost and you will need to
+re-create them (step 2).  If you unpacked the Eigen library in this
+directory (as opposed to somewhere else on your system), you will also
+need to repeat step 1.
+
+The Makefile.lammps file in this directory is there for compatibility
+with the way other libraries under the lib dir are linked with by
+LAMMPS.  However, the Eigen library requires no auxiliary files or
+settings, so its variables are blank.
