    initial v1  
    1717* Clean up the atlas SPKG a bit so it's only responsible for installing ATLAS if requested.
    1818
    19 * Add a generic package called just "blas" (we could keep openblas as the default though).  The spkg-configure.m4 for blas would implement the `--with-blas` flag, and also extend it to take an optional argument of a path (e.g. instead of --with-blas=openblas` or `--with-blas=atlas` one can pass something like `--with-blas=/usr/lib`.  This latter case would have essentially functionality as the current `SAGE_ATLAS_LIB` (maybe a little better): use that path to search for a generic blas library; maybe also check that it contains some known symbols.

    2020  * This is nice, because if you use the `--with-blas=<path>` option you don't get any SPKGs installed for blas, emphasizing that some generic blas on the system is being used.
