Installing Addons in IPCOP - How?

[lmfy2k]

Hi guys

got IPCOP installed and its running fine (i think!)

I want to install DansGuardian, ive downloaded it and its come down as a dansguardian.tar.gz file

now im a noob in Linux, how on earth do i install it in ipcop?

i cant see any option in the webgui to install addons

i can connect to my ipcop box using winscp, if thats any use!

anyone shed any light?

thanks
