# Notes #
################################################################################
# A note on reset, restore, and revert, paraphrased from `man git`, plus my own
# on `rm`:
#
# revert - make a new commit that reverts a previous commit.
# restore - undo uncommitted changes in the working tree.
# reset - update the branch and change commit history.
# rm - same as system rm; remove files, either from git's knowledge, the working
# directory, or both.
#
# These are not a description of the *possible* uses, rather a narrowing of the
# *intended* uses.
# - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
# PATH VALUES:
# :/ - all files within the root of the working tree, so all files in the repo,
# a la git add's --all option.
