+// CrashReportSender is a "static" class which provides an API to upload
+// crash reports via HTTP(S).  A crash report is formatted as a multipart POST
+// request, which contains a set of caller-supplied string key/value pairs,
+// and a minidump file to upload.
+//
+// To use this library in your project, you will need to link against
+// wininet.lib.
