DirChex_v1.3 has been created for BackTrack 4 (should also work for most Debian distros).
This is the GUI version which also has can test an App for vulnerable PUT enabled directories.
So, two new releases two different programs. Busy day.
Also, due to some requests for a Non-GUI (Console based) only version of DirChex this will be in the works along with some added features for path mutation.
