/* Extension testsuite
 * -------------------
 *
 * Authors: Stephan Bosch
 * Specification: vendor-specific
 *   (FIXME: provide specification for test authors)
 *
 */

/*
 * Purpose: This custom extension is used to add sieve commands and tests that
 *          act the Sieve engine and on the test suite itself. This practically
 *          provides the means to completely control and thereby test the Sieve
 *          compiler and interpreter. This extension transforms the basic Sieve
 *          language into something much more powerful and suitable to perform
 *          complex self-test operations. Of course, this extension is only
 *          available (as vnd.dovecot.testsuite) when the sieve engine is used
 *          from within the testsuite commandline tool. Test scripts have the
 *          extension .svtest by convention to distinguish them from any normal
 *          sieve scripts that may reside in the same directory.
 *
 * WARNING: Although this code can serve as an example on how to write
 *          extensions to the Sieve interpreter, it is generally _NOT_ to be
 *          used as a source for ideas on new Sieve extensions. Many of the
 *          commands and tests that this extension introduces conflict with the
 *          goal and the implied restrictions of the Sieve language. These
 *          restrictions were put in place with good reason. Therefore, do
 *          _NOT_ export functionality provided by this testsuite extension to
 *          your custom extensions that are to be put to general use.
