+# This file contains a list of commits that are not likely what you

+# You can set this file as a default ignore file for blame by running
+# the following command.

+# $ git config blame.ignoreRevsFile .git-blame-ignore-revs

+# To temporarily not use this file add
+# --ignore-revs-file=""
+# to your blame command.

+# The ignoreRevsFile can't be set globally due to blame failing if the file isn't present.
+# To not have to set the option in every repository it is needed in,
+# save the following script in your path with the name "git-bblame"
+# now you can run
+# $ git bblame $FILE
+# to use the .git-blame-ignore-revs file if it is present.
