# Goals of this file:
# - Prevent untracked (gitignore'd) files from affecting the build
# - Cache as much as possible to allow quick iteration
#
# Hence the aria2 build should be cached since it rarely changes and takes about 5 times as long to
# build as the updater. To permit caching, the aria2 directory needs to be copied separately before
# the rest of updater2.
#
# git clean -dXff is used to delete all the files specified by .gitignore. This requires the data
# from .git since a checked-in file will not be ignored. For aria2 it is assumed that the data
# is stored in the updater2/.git/modules directory.
