-All symbols used internally in libcurl must use a `Curl_` prefix if they are
-used in more than a single file. Single-file symbols must be made static.
-Public ("exported") symbols must use a `curl_` prefix. Public API functions
-are marked with `CURL_EXTERN` in the public header files so that all others
-can be hidden on platforms where this is possible.
