[`libprecious`](https://npm.im/libprecious) installs npm projects in a way
that's optimized for continuous integration/deployment/etc scenarios. It gives
up the ability to build its own trees or install packages individually, as well
as other user-oriented features, in exchange for speed, and being more strict
about project state.
For documentation about the associated command-line tool, see
[`my-precious`](https://npm.im/my-precious).
## Install
`$ npm install libprecious`

### Features
* saves all your dependency tarballs to local files
* npm-compatible caching
* errors if `package.json` and `package-lock.json` are out of sync, instead of fixing it like npm does. Essentially provides a `--frozen` install.

## ACKNOWLEDGEMENTS
`libprecious` is a reimplementation of the concept of
[`shrinkpack`](https://npm.im/shrinkpack), with the intention of integrating it
directly into npm itself, and using common libraries for increased
compatibility.
The `libprecious` team is grateful to Jamie Mason and the rest of the
`shrinkpack` developers for their support and encouragement!
