The bin script that runs chromium calls out to gnugrep - but gnugrep is
missing as a runtime dependency of the chromium package. I found this
out when I was trying to put it in a docker image.
"bazel fetch" will, by default, fetch everything that _might_ be used,
including things that will later be discarded due to the way the build
is configured.
Concretely, this means that for some builds of Java packages, this will
avoid failures where the builder tries to retrieve the JDK from /usr/share/java
(or equivalent).
This also means that for most packages we can fetch _fewer_ dependencies,
since the standard tree pruning for artifacts to fetch will take effect.
fetchConfigured is disabled by default since it changes the fetch hashes
of tensorflow/tensorflow2 (since it ends up fetching less).
Preserving existing behavior: the bash completion was not executable,
the zsh completion was; according to lukegb the fish completion does
not have to be executable.

- Begin a new chapter "GPU Acceleration", this should also cover
VA-API, OpenGL, Vulkan, etc.
- Add a general blurb about OpenCL and how to check whether OpenCL
devices are found.
- Add a section about enabling OpenCL for AMD GPUs specifically.
This utility reports information about AMD GPUs that are supported by
the ROCm stack. It also exposes functionality for clock and
temperature management.
