+Quick helper script for proxmark3 client when working with a Proxmark3 device
+
+Description:
+    The usage is the same as for the proxmark3 client, with the following differences:
+     * the correct port name will be automatically guessed;
+     * the script will wait for a Proxmark3 to be connected (same as option -w of the client).
+    You can also specify a first option -n N to access the Nth Proxmark3 connected.
+    To see a list of available ports, use --list.
+
+Usage:
+    $SCRIPT [-n <N>] [<any other proxmark3 client option>]
+    $SCRIPT [--list] [-h|--help] [-hh|--helpclient]
+    $SCRIPT [-o|--offline]
+
+
+Arguments:
+    -h/--help        this help
+    -hh/--helpclient proxmark3 client help (the script will forward these options)
+    --list           list all detected com ports
+    -n <N>           connect device referred to the N:th number on the --list output
+    -o/--offline     shortcut to use directly the proxmark3 client without guessing ports
+
+Samples:
+    ./$SCRIPT                       -- Auto detect/ select com port in the following order BT, USB/CDC, BT DONGLE
+    ./$SCRIPT -p /dev/ttyACM0       -- connect to port /dev/ttyACM0
+    ./$SCRIPT -n 2                  -- use second item from the --list output
