The man pages for various commands (such as dotnet-build) indicate they are generated from some other document using a tool:

$ head -1 ./dotnet-sdk-2.0.0-preview2-006497/src/cli/Documentation/manpages/sdk/dotnet-compile.1
.\" Automatically generated by Pandoc 1.15.1

What is the process to update these docs? Where can I find that original source?
