amtm is a front end that manages popular scripts for wireless routers running
Asuswrt-Merlin firmware.
Starting with Asuswrt-Merlin 384.15, amtm is included in the firmware.
amtm is intended to be a helper script, a convenient shortcut manager to install and manage scripts on your router.
The idea for such a helper was suggested by a SmallNetBuilder Forums member and promptly coded and continually improved on.
Note that the firmware built-in and the regular amtm version receive updates at the same time.
