 #
 # * Minimum perl officially supported by DBIC is 5.8.3. This *includes* the
 # basic depchain. On failure either attempt to fix it or bring it to the
-# attention of ribasushi. *DO NOT* disable 5.8 testing - it is here for a
-# reason
-#
-# * The matrix is built from two main modes - CLEANTEST = [true|false].
-# - In the first case we test with minimal deps available, and skip everything
-#   listed in DBIC::OptDesps. The modules are installed with classic CPAN
-#   invocations and are *fully tested*. In other words we simulate what would
-#   happen if a user tried to install on a just-compiled virgin perl
-# - Without CLEANTEST we bring the armada of RDBMS and install the maximum
-#   possible set of deps *without testing them*. This ensures we stay within
-#   a reasonable build-time and still run as many of our tests as possible
-#
-# * The perl builds and the DBIC tests run under NUMTHREADS number of threads.
-# The testing of dependencies under CLEANTEST runs single-threaded, at least
-# until we fix our entire dep-chain to safely pass under -j
-#
-# * The way .travis.yml is fed to the command controller is idiotic - it
-# makes using multiline `bash -c` statements impossible. Therefore to
-# aid readability (our travis logic is rather complex), the bulk of
-# functionality is moved to scripts. More about the problem (and the
-# WONTFIX "explanation") here: https://github.com/travis-ci/travis-ci/issues/497
+# attention of the maintainer. *DO NOT* disable 5.8 testing - it is here for
+# a very good reason

 # the entire run times out after 50 minutes, or after 5 minutes without
