Let people who run the nightly tester specify paths to external tests, instead of having to hack the nightly tester script itself.
Let people who run the nightly tester specify paths to external tests, instead
of having to hack the nightly tester script itself.

as an example, I use the following for my machine:

$HOME/llvm/utils/NightlyTest.pl -parallel -release -enable-llcbeta \
     -spec2000path /Volumes/ProjectsDisk/cvs/benchmarks/speccpu2000-llvm/benchspec/ \
     -povraypath /Volumes/ProjectsDisk/cvs/benchmarks/povray31 \
     -namdpath /Volumes/ProjectsDisk/cvs/benchmarks/namd
