+## Hexadecimal decoding

+In the preprocess stage, a special instruction can be used to have runtests.pl
+generate a sequence of binary bytes.
+
+To insert a sequence of bytes from a hex encoded string, use this syntax:
+
+ %hex[ %XX-encoded data to decode ]hex%
+
+For example, to insert the binary octets 0, 1 and 255 into the test file:

+ %hex[ %00%01%FF ]hex%
