+Structural variables
+--------------------
+
+Pandoc sets these variables automatically in response to [options] or
+document contents; users can also modify them. These vary depending
+on the output format, and include the following:
+
+`body`
+:   body of document
+
+`header-includes`
+:   contents specified by `-H/--include-in-header` (may have multiple
+    values)
+
+`include-before`
+:   contents specified by `-B/--include-before-body` (may have
+    multiple values)
+
+`include-after`
+:   contents specified by `-A/--include-after-body` (may have
+    multiple values)
+
+`meta-json`
+:   JSON representation of all of the document's metadata. Field
+    values are transformed to the selected output format.
+
+`numbersections`
+:   non-null value if `-N/--number-sections` was specified
+
+`sourcefile`, `outputfile`
+:   source and destination filenames, as given on the command line.
+    `sourcefile` can also be a list if input comes from multiple files, or empty
+    if input is from stdin. You can use the following snippet in your template
+    to distinguish them:
+
+        $if(sourcefile)$
+        $for(sourcefile)$
+        $sourcefile$
+        $endfor$
+        $else$
+        (stdin)
+        $endif$
+
+    Similarly, `outputfile` can be `-` if output goes to the terminal.
+
+`toc`
+:   non-null value if `--toc/--table-of-contents` was specified
+
+`toc-title`
+:   title of table of contents (works only with EPUB,
+    opendocument, odt, docx, pptx, beamer, LaTeX)
