The source distribution contains a subdirectory perl/, which contains a small test suite for comparing the behaviour of libsrs2 with the behaviour of the reference implementation Mail::SRS.
Feel free to run this testsuite. If you extend it, please send patches back to srs [ta] anarres.org. To run the test suite, build libsrs2, then from the perl/ subdirectory, type:
libsrs2 is a compliant library and may be used as a "gold standard" for testing other implementations. We aim to provide bindings for various languages to make this easier. If you write bindings for libsrs2 to a new language, please send them to shevek [ta] anarres.org for inclusion in the project.
