WIP on binary packages
Merge branch 'master' into binary-packages
Merge branch 'master' into binary-packages
Faster binary rewriter
Encode platform in package name
Remove defunct binary rewriter
Add --verbose and --resume options
ruby-package
Fix cleanup
Just use ruby-build from $PATH
Add TODO
ruby-package fetch --check
Better error and progress messages
ruby-package install --fail-silently
rbenv-install tries to install packages by default, then falls back to building
Remove --force- prefix
Handle the case when there is no processor info in `/proc/cpuinfo`

`grep -c` would correctly output "0", which is handled specially later
on, but would also exit with a nonzero status which would abort the
script. Piping the output to `wc` to do the counting makes the exit
status of grep irrelevant.
