This directory contains CGManifest (cgmanifest.json) files. See here for details: https://docs.opensource.microsoft.com/tools/cg/cgmanifest.html

cgmanifests/cgmanifest.json contains entries that don't belong in more specific categories (e.g., git submodules).

cgmanifests/submodules/cgmanifest.json contains entries for git submodules. It can be generated like this:

1. Change to the repository root directory.
2. Ensure the submodules are checked out. For example, with:

   $ git submodule update --init --recursive
   

3. Run the generator script:

   $ python cgmanifests/submodules/generate_submodule_cgmanifest.py > cgmanifests/submodules/cgmanifest.json
   

Please update this cgmanifest.json file when any git submodules change.
