+Portable to at least ABCL, Allegro CL (with one problem with inlining
+settings), SBCL, CCL and CLISP. CMUCL possibly, but not tested on
+Travis CI. ECL fails on Travis CI ([`OPTIMA`][3] fails there as well),
+but runs successfully on my own machine, so YMMV. See the detailed
+reports at
+[https://travis-ci.org/Ferada/cl-mock](https://travis-ci.org/Ferada/cl-mock)
+for more information and [`CL-TRAVIS`][5], and [`.travis.yml`][6] for the
+setup.
