# batch install missing packages reported by `bundle package`

# When `bundle package', it might complain: "Could not find charlock_holmes-0.6.9.1.gem for installation",
# You have to run `gem install charlock_holmes -v 0.6.9.1' and run `bundle package` again
# And it might complain another package missing, then you have to run `gem install foobar -v xxxxx`
# Again, and again. Thus I have this little script
