Although it does look like we can remove atlas since {blas,lapack}-atlas are stable on the same keywords, we can't do so for blas and lapack yet because *-reference aren't stable on (blas) x86 s390 ppc64 (lapack) x86 or ~arch on (lapack) ppc64. > * cblas/clapack: as mentioned in a previous post, at least a > virtual/cblas could help (as well as a cblas-reference) ebuild. cblas-reference seems to have appeared at some point in the past couple of months. > * documentation: shouldn't blas/lapack install man pages and quick > references as well as in Fedora (or may be an app-docs/lapack)? Sounds useful. Got a patch?
