+# Some overall notes on how this works
+#
+# * We smoke using the system provided latest, and custom built "oddball perls"
+# The reason for not having a blanket matrix is to conserve travis resources
+# as a full DBIC depchain isn't cheap
+#
+# * 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
