-# syn-protobuf.sh is a bash script to sync the protobuf
-# files using the proto-compiler project. It will check
-# out the protobuf files from the git versions specified in
-# proto/src/prost/COSMOS_SDK_COMMIT and
-# proto/src/prost/IBC_GO_COMMIT. If you want to sync
-# the protobuf files to a newer version, modify the
-# relevant files with the new commit IDs.
-
-# This script should be run from the root directory of ibc-rs
-
-# We can specify where to clone the git repositories
-# for cosmos-sdk and ibc-go. By default they are cloned
-# to /tmp/cosmos-sdk.git and /tmp/ibc-go.git.
-# We can override this to existing directories
-# that already have a clone of the repositories,
-# so that there is no need to clone the entire
-# repositories over and over again every time
-# the script is called.
