# This script is used by the commit hook to detect if there are changes in the

# sorted section. Developers may commit to kernel-source without having changed

# the sorted section and used the git-sort tools, therefore without having the

# pygit2 module available. Therefore, this script should avoid a dependency on

# pygit2 since it's not present on a default python install and we don't want to

# force developers to install pygit2 just to commit unrelated changes to

# kernel-source.
