+@node Cryptographic and Hash Procedures
+@section Cryptographic and Hash Procedures
+
+This module links libcrypto, exposing some hash procedures.
+
+@defun sha256 message
+Calculate the sha256-sum of @var{message}. The message can either be a
+bytevector or a string (in which case it will de encoded as UTF-8).
+
+Returns the checksum as a bytevector.
+@end defun
+
+@defun checksum->string message-digest [port]
+Generates a hex digest string from a checksum (generated by
+@code{sha256}). The checksum is written to @var{port} if given, or
+returned as a string otherwise.

+@node Graphviz
+@section Graphviz
+
+The graphviz library comes bundled with Guile bindings, but without a
+corresponding .scm file exporting the symbols. The module @code{(guile)} does
+exactly that.
+
+This ``header'' is borrowed from
+@url{https://github.com/roelj/graphviz-guile/blob/master/graphviz.scm},
+under GPL 3.0.
