+// Package bundler provides an API for creating certificate bundles,
+// which contain a trust chain of certificates. Generally, the bundles
+// will also include the private key (but this is not strictly
+// required). In this package, a bundle refers to a certificate with
+// full trust chain -- all certificates in the chain in one file or
+// buffer.
+//
+// The first step in creating a certificate bundle is to create a
+// Bundler. A Bundler must be created from a pre-existing certificate
+// authority bundle and an intermediate certificate bundle. Once the
+// Bundler is initialised, bundles may be created using a variety of
+// methods: from PEM- or DER-encoded files, directly from the relevant
+// Go structures, or by starting with the certificate from a remote
+// system. These functions return a Bundle value, which may be
+// serialised to JSON.
