If all that looks a _lot_ like standard `git`, that's no coincidence; it's
a design feature.

+`vcsh` store the actual files in `$HOME` but you can override this setting if
+you want to.
All this means that you can have one repository per application or application
family, i.e. `zsh`, `vim`, `ssh`, etc. This, in turn, allows you to clone
custom sets of configurations onto different machines or even for different
or available to root and you may want to maintain different configuration for
`ssh` on your personal and your work machines.
-`vcsh` was designed with [mr][mr] in mind so you might want to install that, as
-well.
+A lot of modern UNIX-based systems offer packages for `vcsh`. In case yours
+does not read `INSTALL.md` for install instructions or `PACKAGING.md` to create
+a package, yourself. If you do end up packaging `vcsh` please let us know so we
+can give you your own packaging branch in the upstream repository.

+# Usage Examples
+
+There are three different ways to interact with `vcsh` repositories; this
+section will only show the simplest and easiest way.
+Certain more advanced use cases require the other two ways, but don't worry
+about this for now. If you never even bother playing with the other two
+modes you will still be fine.
+`vcsh enter` and `vcsh run` will be covered in later sections.

# Overview
-## Comparison to Other Solutions ##
+## From zero to vcsh
+
+You put a lot of effort into your configuration and want to both protect and
+distribute this configuration.
Most people who decide to put their dotfiles under version control start with a
single repository in `$HOME`, adding all their dotfiles (and possibly more)
downsides of this approach are the necessary manual steps of cloning and
symlinking the individual repositories.
-`vcsh` takes this second approach one step further. It expects
-single-purpose repositories and stores them in a hidden directory (similar
-to `~/.dotfiles`). However, it does not create symbolic links in `$HOME`; it
-puts the actual files right into `$HOME`.
+`vcsh` takes this approach one step further. It enables single-purpose
+repositories and stores them in a hidden directory. However, it does not create
+symbolic links in `$HOME`; it puts the actual files right into `$HOME`.
+
+As `vcsh` allows you to put an arbitrary number of distinct repositories into
+your `$HOME`, you will end up with a lot of repositories very quickly.
+
+To manage both `vcsh` and other repositories, we suggest using [mr](mr). `mr`
+takes care of pulling in and pushing out new data for a variety of version
+control systems.
+
+`vcsh` was designed with [mr][mr], a tool to manage Multiple Repositories, in
+mind and the two integrate very nicely. `mr` has native support for `vcsh`
+repositories and to `vcsh`, `mr` is just another configuration to track.
+This make setting up any new machine a breeze. It takes literally less than
+five minutes to go from standard installation to fully set up system
-Furthermore, by making use of [mr][mr], it makes it very easy to enable/disable
-and clone a large number of repositories. The use of `mr` is technically
-optional (see section 4.3), but it will be an integral part of the proposed
-system that follows.

-## Default Directory Layout ##
+## Default Directory Layout
To illustrate, this is what a possible directory structure looks like.
|-- .mrconfig
`-- .mrtrust
-### available.d ###
+### available.d
The files you see in $XDG\_CONFIG\_HOME/mr/available.d are mr configuration files
that contain the commands to manage (checkout, update etc.) a single
[$XDG_CONFIG_HOME/vcsh/repo.d/zsh.git]
checkout = vcsh clone 'git://github.com/RichiH/zshrc.git' zsh
- update = vcsh run zsh git pull
- push = vcsh run zsh git push
- status = vcsh run zsh git status
- gc = vcsh run zsh git gc
+ update = vcsh zsh pull
+ push = vcsh zsh push
+ status = vcsh zsh status
+ gc = vcsh zsh gc
-### config.d ###
+### config.d
$XDG\_CONFIG\_HOME/mr/available.d contains *all available* repositories. Only
files/links present in mr/config.d, however, will be used by mr. That means
be checked out. A simple `mr update` run in $HOME will clone or update those
four repositories listed in config.d.
-### ~/.mrconfig ###
+### ~/.mrconfig
Finally, ~/.mrconfig will tie together all those single files which will allow
you to conveniently run `mr up` etc. to manage all repositories. It looks like
this:
[DEFAULT]
- jobs = 5
- # Use if your mr does not have vcsh support in mainline, yet
- include = cat /usr/share/mr/vcsh
include = cat ${XDG_CONFIG_HOME:-$HOME/.config}/mr/config.d/*
-### repo.d ###
+### repo.d
$XDG\_CONFIG\_HOME/vcsh/repo.d is the directory where all git repositories which
are under vcsh's control are located. Since their working trees are configured
to be in $HOME, the files contained in those repositories will be put in $HOME
directly.
-Of course, [mr] [1] will work with this layout if configured according to this
+Of course, [mr] [mr] will work with this layout if configured according to this
document (see above).
vcsh will check if any file it would want to create exists. If it exists, vcsh
will throw a warning and exit. Move away your old config and try again.
Optionally, merge your local and your global configs afterwards and push with
-`vcsh run foo git push`.
+`vcsh foo push`.

+## Moving into a New Host
To illustrate further, the following steps could move your desired
configuration to a new host.
example: `vcsh clone git://github.com/RichiH/vcsh_mr_template.git mr`
2. Choose your repositories by linking them in config.d (or go with the default
you may have already configured by adding symlinks to git).
-3. Make sure the line 'include = cat /usr/share/mr/vcsh' in .mrconfig points
- to an existing file
-4. Run mr to clone the repositories: `cd; mr update`.

repositories by running the necessary vcsh commands for you. You may choose not
to use mr, in which case you will have to run those commands manually or by
other means.
-#### A Few Examples ####
To initialize a new repository: `vcsh init zsh`
To interact with a repository, use the regular Git commands, but prepend them
with `vcsh run $repository_name`. For example:
- vcsh run zsh git status
- vcsh run zsh git add -f .zshrc
- vcsh run zsh git commit
+ vcsh zsh status
+ vcsh zsh add .zshrc
+ vcsh zsh commit
Obviously, without mr keeping repositories up-to-date, it will have to be done
manually. Alternatively, you could try something like this:
