+#!/usr/bin/perl
+
+# This plugin allows your page templates to include Flattr buttons, so
+# Flattr buttons are automatically added on every page that uses the template.
+# If you don't specify a thing ID with the flattrthing directive, it adds
+# auto-submit buttons so things are created when the button is clicked the first
+# time.
+#
+# The plugin is customizable through the following configuration options:
+# - flattrthing_pagespec: allows you to specify a pagespec on which pages the
+#   plugin is active. If empty, no Flattr buttons are generated at all.
+# - flattrthing_defaultuser: sets the default user that owns the Flattr things
+#   which are created by the auto-submit buttons.
+#
+# Also, the plugin adds the flattrthing directive, which allows you to customize
+# the behaviour for one page. It knows the following parameters:
+# - id: the Flattr thing ID (like in http://flattr.com/thing/12341234). If you
+#   specify this option, a button with a thing URL is generated instead of an
+#   auto-submit button. This allows you to link to things which already exist
+#   by the time you create your page.
+# - user: a Flattr username that owns the thing created by the generated
+#   auto-submit button. This parameter has no effect when an ID is specified,
+#   since in this case, the owner is already known to Flattr.
+#
+# This plugin sets the following template variables which your templates should
+# process and generate the according buttons with the right URLs:
+# - FLATTR_ENABLE: contains a truthful value if the page matches the pagespec
+#   configured with flattrthing_pagespec. You can use it with TMPL_IF to
+#   generate code specific to pages which have a Flattr button.
+# - FLATTR_THING_ID: if a thing ID was specified with the flattrthing directive,
+#   this variable contains the ID that was given in the directive.
+# - FLATTR_THING_ID_SET: contains a thurthful value if FLATTR_THING_ID is set.
+# - FLATTR_USER: contains the username that was specified with the flattrthing
+#   directive, or if that was not the case, the username that was configured
+#   with flattrthing_defaultuser in your setup file.
+# - FLATTR_THING_URL: contains the full URL to the page.
