+
+        UPC-E barcodes can be expressed in 6, 7, or 8-digit formats, but this
+        method uses the 8 digit format, since it is trivial to convert to the
+        other two formats. The first digit (starting from the left) is

+        UPC-E barcode's UPC-A equivalent. The middle six digits are collectively
+        referred to as the ``base`` (for a lack of a better term).
+
+        On that note, this method uses ``base`` and ``number_system_digit`` to
+        first generate a UPC-A barcode for the check digit, and what happens
+        next depends on the value of ``safe_mode``. The argument ``safe_mode``
+        exists, because there are some UPC-E values that share the same UPC-A
+        equivalent. For example, any UPC-E barcode of the form ``abc0000d``,
+        ``abc0003d``, and ``abc0004d`` share the same UPC-A value
+        ``abc00000000d``, but that UPC-A value will only convert to ``abc0000d``
+        because of (a) how UPC-E is just a zero-suppressed version of UPC-A and
+        (b) the rules around the conversion.
+
+        If ``safe_mode`` is ``True`` (default), this method performs another set
+        of conversions to guarantee that the UPC-E barcodes generated can be
+        converted to UPC-A, and that UPC-A barcode can be converted back to the
+        original UPC-E barcode. Using the example above, even if the bases
+        ``120003`` or ``120004`` are used, the resulting UPC-E barcode will

+
