# OK, so there's some weirdness in this file. Basically, this weirdness is for a few reasons:
# - we want to use the cache of Travis if possible. If things are cached we don't want to recompile.
# - sudo make install can sometimes fail due to travis not making clang available to sudo
#   - so, we use -E and -i. However, -i moves to root homedirectory, so we need to switch back
#   - but doing that on one command line with sudo in bash is not fantastic. easier to have a
#     separate helper script so that we can do this. however, since the helper script is in the
#     source distribution we also need to keep track of the current directory, and use absolute
#     paths for those things
# - all of this horribleness would probably be easier solved by rejigging everything to install
#   in a local lib/include directory, but that caused conflicts with system installed things
#   sometimes, so it would need more investigation and work to make it functional.
