New page

==ETISnoop==

ETISnoop is a small too developed by CSP.it that can '''decode some FIC information''' from a ETI file. It is in the mmbtools-aux repository:
https://github.com/mpbraendli/mmbtools-aux/tree/master/etisnoop

===Compilation===

There is only a very simple makefile, so no ''make install'' and similar.

To compile etisnoop:

git clone https://github.com/mpbraendli/mmbtools-aux.git
cd mmbtools-aux/etisnoop
make

===Usage===
