Problem:    It is not easy to use a set of plugins and their dependencies.
Solution:   Add packages, ":loadopt", 'packpath'.

-5. Debugging scripts					*debug-scripts*
+5. Using Vim packages					*packages*
+
+A Vim package is a directory that contains one or more plugins.  The
+advantages over normal plugins:
+- A package can be downloaded as an archive and unpacked in its own directory.
+  That makes it easy to updated and/or remove.
+- A package can be a git, mercurial, etc. respository.  That makes it really
+  easy to update.
+- A package can contain multiple plugins that depend on each other.
+- A package can contain plugins that are automatically loaded on startup and
+  ones that are only loaded when needed with `:loadplugin`.
+
+Let's assume your Vim files are in the "~/.vim" directory and you want to add a
+package from a zip archive "/tmp/mypack.zip":
+	% mkdir -p ~/.vim/pack/my
+	% cd ~/.vim/pack/my
+	% unzip /tmp/mypack.zip
+
+The directory name "my" is arbitrary, you can pick anything you like.
+
+You would now have these files under ~/.vim:
+	pack/my/README.txt
+	pack/my/ever/always/plugin/always.vim
+	pack/my/ever/always/syntax/always.vim
+	pack/my/opt/mydebug/plugin/debugger.vim
+
+When Vim starts up it scans all directories in 'packpath' for plugins under the
+"ever" directory and loads them.  When found that directory is added to
+'runtimepath'.
+
+In the example Vim will find "my/ever/always/plugin/always.vim" and adds 
+"~/.vim/pack/my/ever/always" to 'runtimepath'.
+
+If the "always" plugin kicks in and sets the 'filetype' to "always", Vim will
+find the syntax/always.vim file, because its directory is in 'runtimepath'.
+
+							*load-plugin*
+To load an optional plugin from a pack use the `:loadplugin` command: >
+	:loadplugin mydebug
+This could be done inside always.vim, if some conditions are met.
+Or you could add this command to your |.vimrc|.
+
+It is perfectly normal for a package to only have files in the "opt"
+directory.  You then need to load each plugin when you want to use it.
+
+Loading packages will not happen if loading plugins is disabled, see
+|load-plugins|.
