# Chaps relies on utility code from Chromium base libraries, at:
CHROMEBASE_GIT=https://chromium.googlesource.com/chromium/src/base.git
# The particular version of the Chromium base library required by platforms2/chaps
# is indicated by the BASE_VER value in platform2/common-mk/BASE_VER
#  - http://crrev.com/$BASE_VER returns a 302-redirect to the corresponding Git commit
#    in the Chromium source code at https://chromium.googlesource.com/chromium/src.
#    Call this SHA_A
#  - However, this is a commit-ID in the master src.git repository, which is huge.
#    We're only interested in code under base/, which gets pulled into a separate
#    (smaller) Git repo base.git.
#  - Running `git log -n 1 $SHA_A base/` in the full src.git repo gives the SHA1
#    for the last commit in src.git that affected base/ and so should also be present
#    (as a copy) in base.git. Call this SHA_B.
#  - Under base.git, running `git log --grep $SHA_B origin/master` gives the
#    corresponding commit in the base.git tree.  Call this SHA_C.
#  - This $SHA_C hash value from base.git is used here.
