There is an entire POD in the script, access by:

> crapps.pl --man
[download]

Basically, you can use:

> crapps.pl devices.txt --ssh --username SSHUSER --password SSHPASS --
+command file.txt --write
[download]

The above uses SSH to connect to each host by IP or hostname, 1 per line, in the file devices.txt using the username SSHUSER and password SSHPASS executing on each device the commands in, 1 per line, in the file file.txt and saving the session transcript in a file by the hostname or IP connected to.

Preparing devices.txt and file.txt as well as parsing the output from the session files is left as an exercise for the reader.
