The \"ihave\" extension provides a means to write scripts that can take advantage of optional Sieve features but can still run when those optional features are not available.  The extension also defines a new error control command intended to be used to report situations where no combination of available extensions satisfies the needs of the script. [STANDARDS-TRACK]",
