+This command removes "extraneous" packages\.  If a package name is
+provided, then only packages matching one of the supplied names are
+removed\.
+.P
+Extraneous packages are packages that are not listed on the parent
+package's dependencies list\.

+variable is set to \fBproduction\fP, this command will remove the packages
+specified in your \fBdevDependencies\fP\|\. Setting \fB\-\-production=false\fP will
