+
+While it may appear that there's an overwhelming amount of documentation and
+while the explanation of the concepts behind `vcsh` needs to touch a few gory
+details of `git` internals, getting started with vcsh is extremely simple.
+
+Let's say you want to version control your `vim` configuration:
+
+ vcsh init vim
+ vcsh vim add ~/.vimrc ~/.vim
+ vcsh vim commit -m 'Initial commit of my Vim configuration'
+ # optionally push your files to a remote
+ vcsh vim remote add origin REMOTE
+ vcsh vim push origin master:master
+
+If all that looks a _lot_ like standard `git`, that's no coincidence, but
+a design feature.
+
+Once you get familiar with `vcsh`, it's strongly suggested that you look
+into more advanced usage scenarios, especially on how to manage your
+`vcsh` and other repositories with [mr][mr].

-vcsh allows you to have several git repositories, all maintaining their working
-trees in $HOME without clobbering each other. That, in turn, means you can have
-one repository per config set (zsh, vim, ssh, etc), picking and choosing which
-configs you want to use on which machine.
+There are several ways to get in touch with the author and a small but committed
+community around the general idea of version controlling your (digital) life.

+# Introduction #
+
+[vcsh][vcsh] allows you to maintain several git repositories in one single
+directory. They all maintain their working trees without clobbering each other
+or interfering otherwise. By default, all git repositories maintained via
+`vcsh` are stored in <$HOME> but you can override this setting if you want to.
+All that 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
+users; picking and mixing which configurations you want to use where.
+For example, you may not need to have your `mplayer` configuration on a server
+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.

+## Comparison to Other Solutions ##
Most people who decide to put their dotfiles under version control start with a
-**single repository in $HOME**, adding all their dotfiles (and possibly more)
+single repository in <$HOME>, adding all their dotfiles (and possibly more)
to it. This works, of course, but can become a nuisance as soon as you try to
manage more than one host.
The next logical step is to create single-purpose repositories in, for example,
-~/.dotfiles and to create **symbolic links in $HOME**. This gives you the
+<~/.dotfiles> and to create symbolic links into <$HOME>. This gives you the
flexibility to check out only certain repositories on different hosts. The
downsides of this approach are the necessary manual steps of cloning and
-symlinking the individual repositories. It will probably become a nuisance when
-you try to manage more than two hosts.
+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**.

To illustrate, this is what a possible directory structure looks like.

| |-- mr

### available.d ###
-The files you see in ~/.config/mr/available.d are mr configuration files that
-contain the commands to manage (checkout, update etc.) a single repository.
-vcsh repo configs end in .vcsh, git configs end in .git, etc. This is optional
-and your preference. For example, this is what a zsh.mrconfig with read-only
-access to my zshrc repo looks likes. I.e. in this specific example, push can
-not work.
+The files you see in $XDG\_CONFIG\_HOME/mr/available.d are mr configuration files

checkout = vcsh clone 'git://github.com/RichiH/zshrc.git' zsh
update = vcsh run zsh git pull
push = vcsh run zsh git push
### config.d ###
-~/.config/mr/available.d contains *all available* repositories. Only
+$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
that in this example, only the zsh, gitconfigs, tmux and vim repositories will
be checked out. A simple `mr update` run in $HOME will clone or update those

- include = cat ~/.config/mr/config.d/*
+ # 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 ###
-~/.config/vcsh/repo.d is the directory into which vcsh clones the git
-repositories. Since their working trees are configured to be in $HOME, the
-files contained in those repositories will be put in $HOME directly (see .zshrc
-above).
-
+$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
+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`.
-## 2.3 Moving into a New Host ##
+## Moving into a New Host ##
To illustrate further, the following steps could move your desired
configuration to a new host.
1. Clone the mr repository (containing available.d, config.d etc.); for
- example: `vcsh clone git://github.com/RichiH/vcsh_mr_template.git`
+ 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. Run mr to clone the repositories: `cd; mr update`.
-4. Done.
+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`.
+5. Done.
Hopefully the above could help explain how this approach saves time by

Make sure none of the following files and directories exist for your test
(user). If they do, move them away for now:
-* ~/.gitignore
+* ~/.gitignore.d
* ~/.mrconfig
-* ~/.config/mr/available.d/mr.vcsh
-* ~/.config/mr/available.d/zsh.vcsh

+* $XDG\_CONFIG\_HOME/vcsh/repo.d/mr.git/
All of the files are part of the template repository, the directory is where
the template will be stored.
apt-get install mr
-#### 3.1.2 Clone the Template ####
+#### Install vcsh ####
+
+#### Debian ####
+
+If you are using Debian Squeeze, you will need to enable backports
+
+ apt-get install vcsh
+
+#### Arch Linux ####
+
+vcsh is availabe via [AUR](https://aur.archlinux.org/packages.php?ID=54164)
+and further documentation about the use of AUR is available
+[on Arch's wiki](https://wiki.archlinux.org/index.php/Arch_User_Repository).

+ tar xfz vcsh-git.tar.gz
+ cd vcsh-git
+ makepkg -s
+ pacman -U vcsh*.pkg.tar.xz
+
+#### From source ####
+If your version of mr is older than version 1.07, make sure to put
+
+ include = cat /usr/share/mr/vcsh
+
+into your .mrconfig .
+
+ # choose a location for your checkout
+ cd $HOME
mkdir -p ~/work/git
- cd !$
- git clone git://github.com/RichiH/vcsh.git vcsh
+ git clone git://github.com/RichiH/vcsh.git
cd vcsh
- ln -s vcsh /usr/local/bin # or add it to your PATH
+ ln -s vcsh /usr/local/bin # or add it to your PATH

+#### Clone the Template ####
+
+ vcsh clone git://github.com/RichiH/vcsh_mr_template.git mr
+
+#### Enable Your Test Repository ####
mv ~/.zsh ~/zsh.bak
mv ~/.zshrc ~/zshrc.bak
- cd ~/.config/mr/config.d/
+ cd $XDG_CONFIG_HOME/mr/config.d/
ln -s ../available.d/zsh.vcsh . # link, and thereby enable, the zsh repository
cd
mr up
-#### 3.1.4 Set Up Your Own Repositories ####
+#### Set Up Your Own Repositories ####
Now, it's time to edit the template config and fill it with your own remotes:
- vim .config/mr/available.d/mr.vcsh
- vim .config/mr/available.d/zsh.vcsh
+ vim $XDG_CONFIG_HOME/mr/available.d/mr.vcsh
+ vim $XDG_CONFIG_HOME/mr/available.d/zsh.vcsh
And then create your own stuff:
vcsh run foo git commit
vcsh run foo git push
- cp .config/mr/available.d/mr.vcsh .config/mr/available.d/foo.vcsh
- vim .config/mr/available.d/foo.vcsh # add your own repo
+ cp $XDG_CONFIG_HOME/mr/available.d/mr.vcsh $XDG_CONFIG_HOME/mr/available.d/foo.vcsh
+ vim $XDG_CONFIG_HOME/mr/available.d/foo.vcsh # add your own repo
Done!
-### 3.2 The Steal-from-Template Way ###
+### The Steal-from-Template Way ###
You're welcome to clone the example repository:
- git clone git://github.com/RichiH/vcsh_mr_template.git
+ vcsh clone git://github.com/RichiH/vcsh_mr_template.git mr
+ # make sure 'include = cat /usr/share/mr/vcsh' points to an exiting file
+ vim .mrconfig
Look around in the clone. It should be reasonably simple to understand. If not,
poke me, RichiH, on Freenode (query) or OFTC (#vcs-home).
-### 3.3 The Manual Way ###
+### The Manual Way ###
This is how my old setup procedure looked like. Adapt it to your own style or
copy mine verbatim, either is fine.
Grab my mr config. see below for details on how I set this up
vcsh clone ssh://<remote>/mr.git
- cd ~/.config/mr/config.d/
+ cd $XDG_CONFIG_HOME/mr/config.d/
ln -s ../available.d/* .
~ % cat ~/.mrconfig
[DEFAULT]
- include = cat ~/.config/mr/config.d/*
+ # adapt /usr/share/mr/vcsh to your system if needed
+ include = cat /usr/share/mr/vcsh
+ include = cat $XDG_CONFIG_HOME/mr/config.d/*
~ % echo $XDG_CONFIG_HOME
/home/richih/.config
~ % ls $XDG_CONFIG_HOME/mr/available.d # random selection of my repos
