Package: wnpp
Severity: wishlist
* Package name    :
node-safe-publish-latest
  Upstream Author :    ljharb
* URL             : https://www.npmjs.com/package/safe-publish-latest

  Programming Lang: javascript
  Description     : Ensure that when you npm publish, the "latest" tag
is only set for the truly latest version.
Adds "safe-publish-latest" to your package.json's "prepublish" script,
and install in-publish.
It will only activate during an actual npm publish - it will silently
do nothing during installs, and will error when run directly.
It is a dev-dependency of node-has-symbols ( #911124 )
