Parallel download
+++++++++++++++++

By default the download and unzip of pre-compiled package binaries from remote servers will happen in parallel,
defaulting to the number of cpu-cores. The configuration ``core.download:parallel=<int-number>`` can change this
behavior. If ``core.download:parallel=0``, then the behavior will be to not use parallelism and do a sequential
download and unzip of precompiled package binaries.
This ``core.download:parallel`` configuration also affects the ``conan download`` command, but for that command
the default at the moment is not to use parallelism, but sequential download.
