# Unlike the main distcc test suite, this program *does* require you
# to manually set up servers on your choice of machines on the
# network, and make sure that they all have appropriate compilers
# installed. The performance measurements obviously depend on the
# network and hardware available.
# It also depends on you having the necessary dependencies to build
# the software. If you regularly build software on Linux you should
# be OK. Some things (the GIMP) will be harder than others.
# On some platforms, it may be impossible to build some targets -- for
# example, Linux depends on having a real-mode x86 assembler, which
# probably isn't installed on Solaris.
# Note that running this program will potentially download many
# megabytes of test data.
# TODO: Support applying patches after unpacking, before building.
# For example, they might be needed to fix -j bugs in the Makefile.
# TODO: In stats, show ratio of build time to slowest build time. (Or
# to first one run?)
# TODO: Allow choice of which compiler and make options to use.
# TODO: Try building something large in C++.
# TODO: Set CXX as well.
# TODO: Add option to run tests repeatedly and show mean and std. dev.
# TODO: Perhaps add option to do "make clean" -- this might be faster
# than unzipping and configuring every time. But perhaps also less
# reproducible.
# TODO: Add option to run tests on different sets or orderings of
# machines.

Compilers can be specified as either "local,N" to run N copies of gcc,

different scenarios to measure. The default is to run a nonparallel
