## 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%
# Variables
When the test is preprocessed, a range of "variables" in the test file will be
