| 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: | |
