132 For some files in TIFFS doing a hex dump with tiffs cat -h (see above) is
133 sufficient for easily understanding the content of the file, but for other files
134 such as RF parameter tables further developer-friendly decoding is greatly
135 desirable. The generic solution is to extract the complete FFS content with
136 tiffs xtr and then apply further tools for analysis, but this fully generic
137 solution involves a lot of clutter. For some TIFFS files which often need to be
138 looked at and for which tiffs cat -h is insufficient, tiffs decode offers a
139 shorthand. The following files can be decoded in this way:
