pico is a module for static contents based on Duplicatable V3 (D3).

Don't forget updating this module after overwritting older version.
And you have to "sync" once on upgrading from 1.1x/1.2x

Though functionally pico looks a successor to TinyD, pico is made as full-scratched module.

TinyD became a deprecated module because pico has been marked as stable.
Of course, you can upgrade your contents from TinyD to pico easily.
