# Travis 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
# Bitcoin Core 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 cache 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.
