+# The test build matrix (stage: test) is constructed to test a wide range of
+# configurations, rather than a single pass/fail. This helps to catch build
+# failures and logic errors that present on platforms other than the ones the
+# author has tested.
+#
+# Some builders use the dependency-generator in `./depends`, rather than using
+# apt-get to install build dependencies. This guarantees that the tester is
+# using the same versions as Gitian, so the build results are nearly identical
+# to what would be found in a final release.
+#
+# In order to avoid rebuilding all dependencies for each build, the binaries
+# are cached and re-used when possible. Changes in the dependency-generator
+# will trigger cache-invalidation and rebuilds as necessary.
+#
+# These caches can be manually removed if necessary. This is one of the very
+# few manual operations that is possible with Travis, and it can be done by a
+# PIVX GitHub member via the Travis web interface [0].
+#
+# Travis CI uploads the cache after the script phase of the build [1].
+# However, the build is terminated without saving the chache if it takes over
+# 50 minutes [2]. Thus, if we spent too much time in early build stages, fail
+# with an error and save the cache.
