+=head2 EMBEDDED POD DOCUMENTATION
+
+The register functions expects strings (actually scalars) for
+documentation, and nobody wants to embed long parts of documentation into
+a string, cluttering the whole script.
+
+Therefore, Gimp::Fu utilizes the Gimp::Pod module to display the full text
+of the pod sections that are embedded in your scripts (see L<perlpod> for
+an explanation of the POD documentation format) when the user hits the
+"Help" button in the dialog box.
+
+Since version 1.094, you can embed specific sections or the full pod
+text into any of the blurb, help, author, copyright and date arguments
+to the register functions. Gimp::Fu will look into all these strings
+for sequences of the form "=pod(section-name)". If found, they will
+be replaced by the text of the corresponding section from the pod
+documentation. If the named section is not found (or is empty, as in
+"=pod()"), the full pod documentation is embedded.
+
+Most of the mentioned arguments have default values (see THE REGISTER
+FUNCTION) that are used when the arguments are either undefined or empty
+strings, making the register call itself much shorter and, IMHO, more
+readable.
