+"""Convert files from LaTeX format to ReStructured Text.
+
+   This converter is meant only for saving keystrokes.  It won't catch
+   everything and it may misformat stuff, so proofread the file after
+   processing.
+
+   "Verbatim" blocks are not converted due to the difficulty in placing the
+   preceding colon(s) and indenting every line.
