# bandaid fix if a CL that got landed has a build dependency bug and all bots

# need to be cleaned up. If you're writing a new CL that causes build
|
|
# dependency problems, fix the dependency problems instead of adding a

|
# landmine.
|
|
#
|
|
# Before adding or changing a landmine consider the consequences of doing so.
|
|
# Doing so will wipe out every output directory on every Chrome developer's
|
|
# machine. This can be particularly problematic on Windows where the directory
|
|
# deletion may well fail (locked files, command prompt in the directory,
|
|
# etc.), and generated .sln and .vcxproj files will be deleted.
|
|
#
|
|
# This output directory deletion will be repeated when going back and forth
|
|
# across the change that added the landmine, adding to the cost. There are
|
|
# usually less troublesome alternatives.
