# A helper script that first builds git-annex using a Singularity image before
# running the bisection command. It should be called from the git-annex source
# tree as
#
#     $ git bisect run /path/to/bisect-git-annex IMAGE CMD...
#
# where IMAGE is the singularity image or, if an image doesn't exist, the path
# to which the Singularity image should be downloaded. CMD will be executed if
# the build completes successfully.
