# TODO
# ~/.vim cannot be overwritten when directory
# ~/.gitignore gives an error when not there already
# Before doing enything check prerequisites:
# - go (min 1.23?)
# - python devel (min 3.11?)
# - make
# - cmake
# Check for the mistake of having submodules not cloned recursively and do it automagically
#
# Unknown errors yet: 
# - fatal: ref HEAD is not a symbolic ref (from make bin/fzf)
# Features:
# - collect result of everything and output in a table which went fine and which failed?
