| `bootleg-stow` | USE AT YOUR OWN RISK. Tries its best to emulate Stow in an environment where it's not available. Should at the very least allow you to install and update these dotfiles without too much headache. |
|
||||
| `deploy-all.sh` | Deploys all packages. Note that I reserve the right to produce packages with conflicting contents, so in the future this may be refined to only deploy a specific subset of packages (base, desktop-common, etc.). |
|
||||
| `submodule-checkout-masters-and-update.sh` | For every submodule in the repo, checks out its master branch (instead of the exact commit specified in the base repo) and then pulls from upstream. Effectively, this updates any submodules in the repo, such as Vim plugins, themes, etc. |
