-# Overview
-
-Describe the intended usage of this charm and anything unique about how this
-charm relates to others here.
-
-This README will be displayed in the Charm Store, it should be either Markdown
-or RST. Ideal READMEs include instructions on how to use the charm, expected
-usage, and charm features that your audience might be interested in. For an
-example of a well written README check out Hadoop:
-http://jujucharms.com/charms/precise/hadoop
-
-Use this as a Markdown reference if you need help with the formatting of this
-README: http://askubuntu.com/editing-help
-
-This charm provides [service][]. Add a description here of what the service
-itself actually does.
-
-Also remember to check the [icon guidelines][] so that your charm looks good
-in the Juju GUI.
-
-# Usage
-
-Step by step instructions on using the charm:
-
-juju deploy servicename
-
-and so on. If you're providing a web service or something that the end user
-needs to go to, tell them here, especially if you're deploying a service that
-might listen to a non-default port.
-
-You can then browse to http://ip-address to configure the service.
-
-## Scale out Usage
-
-If the charm has any recommendations for running at scale, outline them in
-examples here. For example if you have a memcached relation that improves
-performance, mention it here.
-
-## Known Limitations and Issues
-
-This not only helps users but gives people a place to start if they want to help
-you add features to your charm.
-
-# Configuration
-
-The configuration options will be listed on the charm store, however If you're
-making assumptions or opinionated decisions in the charm (like setting a default
-administrator password), you should detail that here so the user knows how to
-change it immediately, etc.
-
-# Contact Information
-
-Though this will be listed in the charm store itself don't assume a user will
-know that, so include that information here:
-
-## Upstream Project Name
-
- - Upstream website
- - Upstream bug tracker
- - Upstream mailing list or contact information
- - Feel free to add things if it's useful for users

-# Overview
-
-This is the base layer for all charms [built using layers][building]. It
-provides all of the standard Juju hooks and runs the
-[charms.reactive.main][charms.reactive] loop for them. It also bootstraps the
-[charm-helpers][] and [charms.reactive][] libraries and all of their
-dependencies for use by the charm.
-
-# Usage
-
-To create a charm layer using this base layer, you need only include it in
-a `layer.yaml` file:
-
-```yaml
-includes: ['layer:basic']
-```
-
-This will fetch this layer from [interfaces.juju.solutions][] and incorporate
-it into your charm layer. You can then add handlers under the `reactive/`
-directory. Note that **any** file under `reactive/` will be expected to
-contain handlers, whether as Python decorated functions or [executables][non-python]
-using the [external handler protocol][].
-
-### Charm Dependencies
-
-Each layer can include a `wheelhouse.txt` file with Python requirement lines.
-For example, this layer's `wheelhouse.txt` includes:
-
-```
-pip>=7.0.0,<8.0.0
-charmhelpers>=0.4.0,<1.0.0
-charms.reactive>=0.1.0,<2.0.0
-```
-
-All of these dependencies from each layer will be fetched (and updated) at build
-time and will be automatically installed by this base layer before any reactive
-handlers are run.
-
-Note that the `wheelhouse.txt` file is intended for **charm** dependencies only.
-That is, for libraries that the charm code itself needs to do its job of deploying
-and configuring the payload. If the payload itself has Python dependencies, those
-should be handled separately, by the charm.
-
-See [PyPI][pypi charms.X] for packages under the `charms.` namespace which might
-be useful for your charm.
-
-### Layer Namespace
-
-Each layer has a reserved section in the `charms.layer.` Python package namespace,
-which it can populate by including a `lib/charms/layer/<layer-name>.py` file or
-by placing files under `lib/charms/layer/<layer-name>/`. (If the layer name
-includes hyphens, replace them with underscores.) These can be helpers that the
-layer uses internally, or it can expose classes or functions to be used by other
-layers to interact with that layer.
-
-For example, a layer named `foo` could include a `lib/charms/layer/foo.py` file
-with some helper functions that other layers could access using:
-
-```python
-from charms.layer.foo import my_helper
-```
-
-### Layer Options
-
-Any layer can define options in its `layer.yaml`. Those options can then be set
-by other layers to change the behavior of your layer. The options are defined
-using [jsonschema][], which is the same way that [action paramters][] are defined.
-
-For example, the `foo` layer could include the following option definitons:
-
-```yaml
-includes: ['layer:basic']
-defines: # define some options for this layer (the layer "foo")
- enable-bar: # define an "enable-bar" option for this layer
- description: If true, enable support for "bar".
- type: boolean
- default: false
-```
-
-A layer using `foo` could then set it:
-
-```yaml
-includes: ['layer:foo']
-options:
- foo: # setting options for the "foo" layer
- enable-bar: true # set the "enable-bar" option to true
-```
-
-The `foo` layer can then use the `charms.layer.options` helper to load the values
-for the options that it defined. For example:
-
-```python
-from charms import layer
-
-@when('state')
-def do_thing():
- layer_opts = layer.options('foo') # load all of the options for the "foo" layer
- if layer_opts['enable-bar']: # check the value of the "enable-bar" option
- hookenv.log("Bar is enabled")
-```
-
-You can also access layer options in other handlers, such as Bash, using
-the command-line interface:
-
-```bash
-. charms.reactive.sh
-
-@when 'state'
-function do_thing() {
- if layer_option foo enable-bar; then
- juju-log "Bar is enabled"
- juju-log "bar-value is: $(layer_option foo bar-value)"
- fi
-}
-
-reactive_handler_main
-```
-
-Note that options of type `boolean` will set the exit code, while other types
-will be printed out.
-
-# Hooks
-
-This layer provides hooks that other layers can react to using the decorators
-of the [charms.reactive][] library:
-
- * `config-changed`
- * `install`
- * `leader-elected`
- * `leader-settings-changed`
- * `start`
- * `stop`
- * `upgrade-charm`
- * `update-status`
-
-Other hooks are not implemented at this time. A new layer can implement storage
-or relation hooks in their own layer by putting them in the `hooks` directory.
-
-**Note:** Because `update-status` is invoked every 5 minutes, you should take
-care to ensure that your reactive handlers only invoke expensive operations
-when absolutely necessary. It is recommended that you use helpers like
-[`@only_once`][], [`@when_file_changed`][], and [`data_changed`][] to ensure
-that handlers run only when necessary.
-
-# Layer Configuration
-
-This layer supports the following options, which can be set in `layer.yaml`:
-
- * **packages** A list of system packages to be installed before the reactive
- handlers are invoked.
-
- * **use_venv** If set to true, the charm dependencies from the various
- layers' `wheelhouse.txt` files will be installed in a Python virtualenv
- located at `$CHARM_DIR/../.venv`. This keeps charm dependencies from
- conflicting with payload dependencies, but you must take care to preserve
- the environment and interpreter if using `execl` or `subprocess`.
-
- * **include_system_packages** If set to true and using a venv, include
- the `--system-site-packages` options to make system Python libraries
- visible within the venv.
-
-An example `layer.yaml` using these options might be:
-
-```yaml
-includes: ['layer:basic']
-options:
- basic:
- packages: ['git']
- use_venv: true
- include_system_packages: true
-```
-
-
-# Reactive States
-
-This layer will set the following states:
-
- * **`config.changed`** Any config option has changed from its previous value.
- This state is cleared automatically at the end of each hook invocation.
-
- * **`config.changed.<option>`** A specific config option has changed.
- **`<option>`** will be replaced by the config option name from `config.yaml`.
- This state is cleared automatically at the end of each hook invocation.
-
- * **`config.set.<option>`** A specific config option has a True or non-empty
- value set. **`<option>`** will be replaced by the config option name from
- `config.yaml`. This state is cleared automatically at the end of each hook
- invocation.
-
- * **`config.default.<option>`** A specific config option is set to its
- default value. **`<option>`** will be replaced by the config option name
- from `config.yaml`. This state is cleared automatically at the end of
- each hook invocation.
-
-An example using the config states would be:
-
-```python
-@when('config.changed.my-opt')
-def my_opt_changed():
- update_config()
- restart_service()
-```
-
-
-# Actions
-
-This layer currently does not define any actions.

-execd/preinstall
-
-It is often necessary to configure and reconfigure machines
-after provisioning, but before attempting to run the charm.
-Common examples are specialized network configuration, enabling
-of custom hardware, non-standard disk partitioning and filesystems,
-adding secrets and keys required for using a secured network.
-
-The reactive framework's base layer invokes this mechanism as
-early as possible, before any network access is made or dependencies
-unpacked or non-standard modules imported (including the charms.reactive
-framework itself).
-
-Operators needing to use this functionality may branch a charm and
-create an exec.d directory in it. The exec.d directory in turn contains
-one or more subdirectories, each of which contains an executable called
-charm-pre-install and any other required resources. The charm-pre-install
-executables are run, and if successful, state saved so they will not be
-run again.
-
- $CHARM_DIR/exec.d/mynamespace/charm-pre-install
-
-An alternative to branching a charm is to compose a new charm that contains
-the exec.d directory, using the original charm as a layer,
-
-A charm author could also abuse this mechanism to modify the charm
-environment in unusual ways, but for most purposes it is saner to use
-charmhelpers.core.hookenv.atstart().
