Please Describe Your Addition

A rollup plugin to bundle modular libraries with sub directories.

Can you explain how this plugin differs from the official https://github.com/rollup/plugins/tree/master/packages/multi-entry plugin?

@shellscape
multi-entry cannot generate output dynamically
let's say I've 5 input but I always got 1 output

[alfredosalzillo]

https://github.com/alfredosalzillo/rollup-plugin-multi-input can be used to bundle modular libraries.

The https://github.com/rollup/plugins/tree/master/packages/multi-entry can't because it only allow using multiple entries but doesn't assure the output directories tree is preserved.

Thanks for that info. This is going to be inherently confusing to users based on the name, due to the existing official plugin. Some questions:

• Is there a more apt name for this module that provides distinction from the official plugin of similar name?
• Is there an opportunity contribute to the multi-entry plugin to enable the options and behaviors that rollup-plugin-mutli-input provides?
