# List all the (known) operations on each AWS service API. This is
# incredibly useful for building well-restricted IAM access
# rules. With this list you can quickly see what "s3:Get*" matches, or
# just glance through and look for something that might be missing and
# breaking your app.

# I can't believe I had to write this myself. I'm pretty sure there
# are a lot of people out there with near-god-mode permission on IAM
