Running `rcup` should remove any plugins that are no longer in use. For
instance, we recently replaced `rename.vim` with `eunuch`. `rcup`
installs the new plugin but does not clean up `rename` from the plugins
directory. The addition of `PluginClean!` does this (without
confirmation).
I wanted to add my own customizations after reading @mike-burns' post on
[`psqlrc`](http://robots.thoughtbot.com/an-explained-psqlrc).
As a result of this change, `.psqlrc` requires that a `.psqlrc.local`
exist in the home folder because `psql` cannot do conditional sourcing
of files in the style that we use in other foundation dotfiles. Touching
the file to ensure it exists (even if blank) prevents `psql` from
exiting with an error if the user does not provide their own custom
configuration.
Additional changes:
* Updating the documentation with regard to which files get excluded.
Previously, the after-up hook would only do a `:BundleInstall` when
installing vundle for the first time. This is inconsistent with the
pre-rcm process, and also less convenient.
The rcm suite is designed to replace the `./install.sh` script found in
this and many other dotfiles repos across GitHub. By using rcm users can
combine multiple dotfiles repos, tag dotfiles, have host-specific
dotfiles, and other powerful features.
This commit removes `install.sh`, updates the README, adds a post-up
hook that vundles the vim bundles, and adds a `rcrc` configuration that
ignores `README.md` and `LICENSE` and sets the dotfiles directory to
just `dotfiles`.
