>+        Catalog all the MSVC warnings providing the message and a link to documentation
>+        for the warning. Some warnings are noted as being against the style guide so they
>+        won't be addressed. All other warnings could potentially be fixed in the codebase.
>+
>+        Additionally the MSVC version is checked to see if it supports a /permissive-
>+        mode, which conforms with the standard. The /experiment:external flag is also used
>+        which lets a warning level be set for a set of external include directories so a
>+        higher warning level can be used for WebKit code. Currently it assumes that any include
>+        in angle brackets is external. In this case `/Wall` is used.
