Deprecate a version of a package
npm.commands.deprecate(args, callback)
This command will update the npm registry entry for a package, providing a deprecation warning to all who attempt to install it.
The 'args' parameter must have exactly two elements:
package[@version]
The version portion is optional, and may be either a range, or a
specific version, or a tag.
message
The warning message that will be printed whenever a user attempts to install the package.
Note that you must be the package owner to deprecate something. See the
owner and adduser help topics.
To un-deprecate a package, specify an empty string ("") for the message argument.
