Configuring pqR
After uncompressing and unpacking the tar archive (with a command such
as "tar xf pqR-2014-02-19.tar.gz"), you should make a directory in
which to build pqR, such as "pqR-2014-02-19-myconfig". It is possible

which to build pqR, such as "pqR-2014-09-20-myconfig". It is possible
to instead build pqR in the source directory, but using a separate
directory is preferable, so that the source directory says clean, and
so that you can create more than one configuration if desired.

\item Changes have been made to configuration options regarding use of BLAS
routines for matrix multiplication, as described below. In part, these
changes are intended to made the default be close to what R Core
releases do (but without the unnecessary inefficiency).

been incorporated or adapted for use in pqR. These provide some
