* Script to manually add metadata re-exports to the @angular/material package generated
|
|
* via the ng_package bazel rule. This is rather special to the @angular/material package,
|
|
* so it hasn't been built into the ng_package rule yet.
|
|
*
|
|
* This is necessary for being able to import Angular constructs from "@angular/material"
|
|
* while still bundling at a per-component level.
