Subject: Using Optimized builds

Since we've started creating optimized builds (on Unix only at the
moment) and people have gotten error logs for them, you need to know how
to use them. It's very simple.

In a local test area (newrel/d0setwa/addpkg/...) all you need to do is,
after all the usual setups:

> srt_setup SRT_QUAL=maxopt
   (to get back to the non-opt: srt_setup SRT_QUAL=default)

then do what you usually do. The above command changes two SRT
variables: SRT_QUAL and SRT_SUBDIR. The latter causes a whole new set of
directories to be created under bin/ lib/ tmp/ so *everything* will be
and needs to be rebuilt.

A couple of "obvious" points:

You *must* have "setup D0RunII" a version which contains a maxopt build
and your .base_release must agree. To find out if a maxopt version
exists:
  ls $SRT_PUBLIC_CONTEXT/bin
and look for ...-maxopt directory. For example, on d0mino:

  > setup D0RunII t01.32.00
  > ls $SRT_PUBLIC_CONTEXT/bin
  IRIX6-KCC_3_4         IRIX6-KCC_3_4-maxopt

So there is both a non-opt and a maxopt build.

We will be adding this information to the release status page:
