Assignment for Attributes in external Scripts

[niall el-assaad]

Hi,
I am writing an external script to be run based upon an authentication.

When the script returns output I am unsure as to what the assignment
operators do,

for example when should I use += vs := vs =

If I look at the exec-program-wait sample script I see:

echo "Reply-Message += \"Hello, %u\","
echo "Reply-Message += \"PATH=$PATH\","
echo Framed-IP-Address = 255.255.255.255

Is this documented anywhere?

thanks,

niall
