I manage qtile-config using (GNU Stow).
Install qtile-config by cloning the git repository. I recommand using ghq.
ghq get https://github.com/helmecke/qtile-config.git
# or
git clone https://github.com/helmecke/qtile-config.git ~/.qtile-config
You can now symlink any configurations you wish to use:
# Enter repository folder
cd $(ghq list -p | grep helmecke/qtile-config)
#or
cd ~/.qtile-config
# Symlink qtile config
stow -t ~ qtile
# Remove qtile symlink
stow -t ~ -D qtile
