IRLP must already be installed and fully configured and working. EchoIRLP uses IRLP code.
Your IRLP node must be running Debian versions of IRLP.
Your node must have the compiler (GCC) and development software installed. This may not have been 
installed from the latest IRLP Linux software CDROM unless you chose to install everything.
You must have registered your EchoLink node via Windows or the EchoLink web site. Your EchoLink node 
must be a -R (repeater) or -L (link) radio node. Once you have your EchoLink node working on the Windows 
client, you will use that configuration information in EchoIRLP install.

It is recommended that you make a backup copy of IRLP using the script 
/home/irlp/scripts/backup_for_reinstall before installing EchoIRLP. Copy the backup file to a safe place. 
You can reinstall IRLP from the backup using an IRLP reinstall script.

/home/irlp/custom/rc.irlp
/home/irlp/custom/custom_decode
/home/irlp/custom/custom_on
/home/irlp/custom/custom_off
/home/irlp/custom/environment

login as root
wget -N --no-check-certificate https://raw.githubusercontent.com/wd5m/echoirlp/master/install/echo-install
    NOTE: If you get an error from wget about "...test encryption failed", try using the following "curl" 
    command and the alternate echo-install-curl script.
    curl -L -o echo-install https://raw.githubusercontent.com/wd5m/echoirlp/master/install/echo-install-curl
chmod +x ./echo-install
./echo-install
Answer the prompts.
Restart IRLP by running /home/irlp/custom/rc.irlp

Some have reported install failures, where the symptom is an empty tbd.conf file. So far, we have not 
been able to debug this. When this occurs, try installing again.
