+tarball url, name@tag, name@version, or name), this command will fetch
+it to the cache, and then copy the tarball to the current working
+directory as \fB<name>\-<version>\.tgz\fP, and then write the filenames out to
+stdout\.
+.P
+If the same package is specified multiple times, then the file will be
+overwritten the second time\.
+.P
+If no arguments are supplied, then npm packs the current package folder\.
