+
+    NOTES
+
+    This command is used to parse configuration files and output the commands.
+
+Using the Tease Command
+=======================
+
+The ``tease`` command may be used to parse a configuration file, providing additional utilities for working with commands.
+
+The ``path`` argument defaults to ``commands.ini``.
+
+Context Variables May be Provided on the Command Line
+-----------------------------------------------------
+
+To supply context variables on the command line:
+
+.. code-block:: bash
+
+    tease -C domain_name:example.com -C domain_tld:example_com
+
+Loading Context Variables from a File
+-------------------------------------
+
+Context variables may be loaded from a file:
+
+.. code-block:: ini
+
+    [domain]
+    name = example.com
+    tld = example_com
+
+The variables above are available as ``section_key``. For example, ``domain_name`` is ``example.com``.
+
+.. code-block:: bash
+
+    tease -V variables.ini
+
+Setting Common Options for All Commands
+---------------------------------------
+
+Rather than include a common parameter in the configuration file, it is possible to specify a common option on the command line.
+
+.. code-block:: bash
+
+    tease -O sudo:yes
+
+The Difference Between Variables and Options
+--------------------------------------------
+
+Variables are used to pre-process configuration files as templates, while common options are passed to *all* command instances.

+.. _how-to:
+
+******
+How To
+******
+
+Create a New Command Overlay
+============================
+
+:ref:`topics-overlays` are used to define the commands supported by a given application, service, or operating system. Commands are defined as a function.
+
+1) Define a Module
+------------------
+
+The first step is to create a new module in which functions will be defined.
+
+.. code-block:: python
+
+    # module_name.py
+    from ..commands import Command
+
+For overlays that represent an operating system, the ``command_exists()`` function is required:
+
+.. code-block:: python
+
+    def command_exists(name):
+        return name in MAPPINGS
+
+
+2) Define Command Function
+--------------------------
+
+The purpose of each function is to provide an interface for instantiating a :py:class:`scripttease.library.commands.base.Command` instance. The example below is taken from the ``posix`` module.
+
+.. code-block:: python
+
+    # module_name.py
+    # ...
+
+    def mkdir(path, mode=None, recursive=True, **kwargs):
+        """Create a directory.
+
+        - path (str): The path to be created.
+        - mode (int | str): The access permissions of the new directory.
+        - recursive (bool): Create all directories along the path.
+
+        """
+        kwargs.setdefault("comment", "create directory %s" % path)
+
+        statement = ["mkdir"]
+        if mode is not None:
+            statement.append("-m %s" % mode)
+
+        if recursive:
+            statement.append("-p")
+
+        statement.append(path)
+
+        return Command(" ".join(statement), **kwargs)
+
+The arguments and any specific keyword arguments are automatically used by the parser, but also serve as a simple interface for programmatic use.
+
+Each function *must* also accept ``**kwargs`` and should set a default for ``comment`` as above.
+
+.. important::
+    Rather than the usual Spinx-based documentation, define the docstring as shown above. This is used to automatically create the documentation for the command.
+
+3) Add Functions to the Mapping
+-------------------------------
+
+The final step adds the function to the mapping. This makes it available to the command factory.
+
+.. code-block:: python
+
+    # module_name.py
+    # ...
+
+    MAPPINGS = {
+        'mkdir': mkdir,
+    }
+
+For overlays that represent an operating system, ``MAPPINGS`` is required -- in addition to ``command_exists()`` above. For commands that are specific to service or application, the name of the dictionary may be anything that is appropriate. For example, ``DJANGO_MAPPINGS``.
+
+Additionally, for an operating system overlay, you may wish to import other mappings and incorporate them into ``MAPPINGS``.
+
+.. code-block:: python
+
+    # module_name.py
+    from ..commands import Command
+    from .common import COMMON_MAPPINGS
+    from .django import DJANGO_MAPPINGS
+    from .pgsql import PGSQL_MAPPINGS
+
+    MAPPINGS = {
+        # ...
+    }
+
+    MAPPINGS.update(COMMON_MAPPINGS)
+    MAPPINGS.update(DJANGO_MAPPINGS)
+    MAPPINGS.update(PGSQL_MAPPINGS)
+
+4) Update Documentation
+-----------------------
+
+Add the command mappings to the ``docs/generate_command_signatures.py`` file. See the script for more details.
+
+Export Commands as a Script
+===========================
+
+You can export commands as a read-to-use script. For example:
+
+.. code-block:: python
+
+    config = Config("commands.ini")
+    if not config.load():
+        print("Bummer!")
+        exit()
+
+    script = config.as_script()
+    print(script)
+
+Post a Message to Slack
+=======================
+
+The slack function may be used to send a message to a Slack channel. This uses the Incoming Webhooks feature, which requires some additional setup.
+
+.. note::
+    The following steps were accurate as of September 2020.
+
+**1.** Log in to Slack and go to `Your Apps`_.
+
+.. _Your Apps: https://api.slack.com/apps
+
+**2.** Create a new Slack app.
+
+**3.** On the next page, select Incoming Webhooks and then toggle activation.
+
+.. image:: /_static/images/slack-1.jpg
+
+**4.** Next click Add new Webhook to Workspace and select the channel to which the message will be posted.
+
+.. image:: /_static/images/slack-2.jpg
+
+.. image:: /_static/images/slack-3.jpg
+
+**5.** Copy the URL for the new webhook to use as the ``url`` parameter for the Slack command.
+
+.. code-block:: ini
+
+    [send a message to slack]
+    slack: "This is a test message."
+    url: the URL you created goes here
+
+Post a Message to Twist
+=======================
+
+The twist function may be used to send a message to Twist, which requires some additional setup.
+
+.. note::
+    The following steps were accurate as of September 2020.
+
+**1.** Log in to Twist and from the profile menu go to Add Integrations. Then click on Build and "Add a new integration".
+
+**2.** Provide the requested info.
+
+.. image:: _static/images/twist-1.png
+
+**3.** After submitting this info, go to Installation. Select a channel and who to notify. Then click "Install integration".
+
+.. image:: _static/images/twist-2.png
+
+**4.** Copy the "Post content manually" URL for use in your configuration file.
+
+.. code-block:: ini
+
+    [post a message to twist]
+    twist: "This is a test message."
+    url: the URL you created goes here
+
+Use Script Tease With Common Kit
+================================
+
+Since the focus of Script Tease is to convert plain text instructions into valid command line statements, it does *not* provide support for executing those statements either locally or remotely. However, The shell component of `python-commonkit`_ *does* provide support for executing commands in local POSIX environments.
+
+.. _python-commonkit: https://docs.develmaycare.com/en/python-commonkit/stable/components/#module-commonkit.shell
+
+Here is an example of how to use these packages together:
+
+.. code-block:: python
+
+    from commonkit.shell import Command
+    from scripttease.parsers.utils import load_commands
+
+    def execute(step):
+        command = Command(
+            step.statement,
+            comment=step.comment,
+            path=step.cd,
+            prefix=step.prefix,
+            shell=step.shell

 Overview
 ========
 
-The Script Tease package takes plain text instructions in INI or YAML (currently untested) format and converts them into valid command line statements for a given platform (currently CentOS and Ubuntu are supported). It does *not* provide support for executing these statements.
+Script Tease is a library and command line tool for generating commands programmatically or (especially) using configuration files.
 
-Architecture
-============
-
-The provided command line interface (the ``tease`` command) loads configuration files containing instructions and may output these as a Bash script or as documentation.
-
-However, it is possible to create your own implementation to provide input and gather output from the Script Tease library.
-
-.. image:: _static/images/architecture-diagram.png
+The primary focus (and limit) is to convert plain text instructions into valid command line statements for a given platform (see `Overlays`_). It does *not* provide support for executing those statements.
 
 Concepts
 ========
 
-Loaders
--------
-
-A Loader instance is responsible for reading configuration files and parsing the contents into a) a command name, b) arguments, c) keyword arguments.
-
-Command instances are *not* created by the loader. This is the job of the :py:func:`scriptease.lib.factories.command_factory`.
-
-Separating Command generation from loading configuration files makes the loader classes simpler, and keeps the overall system more flexible.
-
-Command Functions
------------------
+Generating Commands
+-------------------
 
-Commands are represented by Python functions. All functions return either a :py:class:`scripttease.lib.commands.base.Command` instance, or in some cases an instance of :py:class:`scripttease.lib.commands.base.MultipleCommands`. (The Template command may also be returned; it is handled specially.)
+Script Tease may be used in two (2) ways:
 
-.. code-block:: python
+1. Using the library to programmatically define commands and export them as command line statements. See :ref:`developer-reference`.
+2. Using the ``tease`` command to generate commands from a configuration file. See :ref:`topics-configuration`.
 
-    def copy(from_path, to_path, overwrite=False, recursive=False, **kwargs):
-        # ...
-
-You could of course use this function directly:
-
-.. code-block:: python
-
-    command = copy("/etc", "/tmp/", recursive=True)
-    print(command.get_statement())
-
-But the point of Script Tease is to take plain text instructions and turn them into command line statements.
-
-Mappings
+Overlays
 --------
 
-So the `copy` function is mapped to a name that may be used in a configuration file:
-
-.. code-block:: python
-
-    MAPPINGS = {
-        # ...
-        'copy': copy,
-        # ...
-    }
+An *overlay* is a set of command meta functions that define the capabilities of a specific operating system.
 
-Such mappings are used by the :py:func:`scriptease.lib.factories.command_factory` to match a command name in a configuration file to the Python function that instantiates the Command.
+.. note::
+    At present, the only fully defined operating system overlays are for Cent OS and Ubuntu.
 
-Configuration File
-------------------
-
-The configuration that invokes this command would like like:
-
-.. code-block:: ini
-
-    [create a copy of the etc directory]
-    copy: /etc /tmp/
-    recursive: yes
-
-Note that the configuration is self-documenting, and in fact, it is possible to output commands as documentation rather than a script.
-
-Variables File
---------------
-
-Prior to a Loader processing commands, configuration files may be parsed as Jinja2 templates. This allows variables to be loaded from a file and passed to the loader as a Context instance.
-
-.. code-block:: ini
-
-    # variables.ini
-    [db_name]
-    comment: The name of the database is the same as the domain name.
-    value: example_app
-
-In the configuration file:
-
-.. code-block:: ini
-
-    [create the database]
-    pgsql.create: {{ db_name }}
-
-Variables are collected in a :py:class:`scripttease.lib.contexts.Context` instance and are passed to the Loader.
+See :ref:`topics-overlays`.

+
+Versioning
+----------
+
+Script Tease follows a loose form of `semantic versioning`_. The use of semantic versioning makes it clear when deprecation occurs and backward compatibility is removed. Documented incompatibilities may still exist where deprecation is not feasible (technically or financially).
+
+.. _semantic versioning: https://semver.org/
+
+Cadence
+-------
+
+New features (and especially new overlays) are planned for release every 3 months. Patch-level changes (to fix bugs or security issues) are always released as needed.
+
+Long-Term Support
+-----------------
+
+Some releases may be designated as long-term support (LTS) releases. Such releases will have security and critical bug fixes applied for 6 months.
+
+Deprecation Policy
+------------------
+
+Minor releases may deprecate features from a previous minor release. For example, if a feature is deprecated in release 1.1, it will continue to work in the 1.2 release, though warnings may be raised. However, the deprecated feature may be removed in release 1.3 and may not function as previously expected or will raise errors.
+
+Major releases may *always* remove deprecated features.
+
+Patch-level releases *never* remove deprecated features.

+Generating Commands From a File
+===============================
+
+The :py:class:`scripttease.parsers.ini.Config` class may instantiate commands by loading a configuration file.
+
+.. note::
+    Additional formats such as JSON or YAML may be supported in the future.
+
+An example file:
+
+.. code-block:: ini
+
+    [install apache]
+    install: apache2
+
+    [create the web site directory]
+    mkdir: /var/www/domains/example_com/www
+    recursive: yes
+
+    [set permissions on the website directory]
+    perms: /var/www/domains/example_com/www
+    group: www-data
+    mode: 775
+    owner: www-data
+
+Notes regarding this format:
+
+- This is the standard format for Python's ConfigParser. If you prefer, you may use ``=`` instead of ``:``.
+- The first part of each command is the INI section and is used as the default comment.
+- The command name *must* be the *first* option in the section.
+- The arguments for the command appear as the value of the first option in the section. Arguments are separated by a
+  space.
+- Arguments that should be treated as a single value should be enclosed in double quotes.
+- ``yes`` and ``no`` are interpreted as boolean values.
+- List values, where required, are separated by commas.
+
+.. _topics-configuration-common-parameters:
+
+Common Parameters
+-----------------
+
+All commands support the following common parameters:
+
+- ``comment``: A comment regarding the command.
+- ``condition``: A condition for execution. For example, ``! -f /path/to/some/file.txt``
+- ``cd``: The path from which a command should be executed.
+- ``environments``: A string or list of comma-separated strings indicating the operational environments in which the command runs. This is *not* used by default, but may be used to programmatically filter commands for a specific environment. For example, development versus live.
+- ``prefix``: A statement to be added prior to executing the command.
+- ``register``: A variable name to which the the success or failure (exit code) of the statement is captured.
+- ``shell``: The shell used to run the commands. For example, ``/bin/bash``. This is generally not important, but can be a problem when attempting to execute some commands (such as Django management commands).
+- ``stop``: ``True`` indicates no other commands should be executed if the given command fails.
+- ``sudo``: ``True`` indicates the command should be automatically prefixed with ``sudo``. If provided as a string, the command is also prefixed with a specific user name.
+- ``tags``: A list of tags used to classify the command.
+
+Defining an "Itemized" Command
+------------------------------
+
+Certain command definitions may be repeated by defining a list of items.
+
+Example of an "itemized" command:
+
+.. code-block:: ini
+
+    [create multiple directories]
+    mkdir: /var/www/domains/example_com/$item
+    items: www, www/assets, www/content
+    recursive:  yes
+
+    [touch a bunch of files]
+    touch: /var/www/domains/example_com/www/$item
+    items: index.html, assets/index.html, content/index.html
+
+.. note::
+    Command itemization may vary with the command type.
+
+Pre-Parsing Command Files as Templates
+======================================
+
+Configuration file may be pre-processed as a Jinja2 template by providing a context dictionary:
+
+.. code-block:: ini
+
+    [install apache]
+    install: apache
+
+    [create the website directory]
+    mkdir: /var/www/domains/{{ domain_tld }}/www
+    recursive: yes
+
+    [set permissions on the website directory]
+    perms: /var/www/domains/{{ domain_tld }}/www
+    group: www-data
+    mode: 775
+    owner: www-data
+
+Then with a config instance:
+
+.. code-block:: python
+
+    context = {
+        'domain_tld': "example_com",
+    }
+
+    config = Config("commands.ini", context=context)
+    config.load()

+# Python Script Tease
+
+## Overview
+
+Script Tease is a library and command line tool for generating Bash commands programmatically and (especially) using configuration files.
+
+The primary focus (and limit) is to convert plain text instructions (in INI or YAML format) into valid command line statements for a given platform. It does *not* provide support for executing those statements.
+
+## Concepts
+
+### Command Generation
+
+Script Tease may be used in two (2) ways:
+
+1. Using the library to programmatically define commands and export them as command line statements. 
+2. Using the `tease` command to generate commands from a configuration file. See [command file configuration](config/command-file.md).
+
+This documentation focuses on the second method, but the developer docs may be used in your own implementation.
+
+### Self-Documenting
+
+The format of INI and YAML files is self-documenting. The command comment is this section (INI) or start of a list item (YAML). This ensures that all commands have a basic description of their purpose or intent.
+
+### Snippets
+
+An *snippet* is simply a tokenized command that may be customized based on the instructions found in a command file. Related snippets are collected into groups and then merged into a larger set that define the capabilities of a specific operating system.
+
+!!! note
+    At present, the only fully defined operating systems are for Cent OS and Ubuntu.
+
+Snippets are defined in Python dictionaries. These include a "canonical" command name as the key and either a string or list which define the command. In both cases, the contents are parsed as Jinja templates. There are various approaches to evaluating  a snippet.
+
+First: The snippet is a simple mapping of command name and command snippet. This is easy. Find the command name in the dictionary, and we have the snippet to be used. For example the `append` command in the `posix` dictionary.
+
+Second: The snippet is a mapping of command name and a list of snippets to be combined. Find the command name in the dictionary, and iterate through the snippets. For example, many of the commands in the `posix` dictionary takes this form. Command identification is the same as the first condition.
+
+Third: The command is a mapping to informal sub-commands. Examples include `apache` and `system` in the `ubuntu` dictionary. There are a couple of ways to handle this in the config file:
+
+- Use the outer command as the command with the inner command as the first (and perhaps only) argument. For example `apache: reload` or `system: upgrade`.
+- Use a "dotted path" to find the command. For example: `apache.reload: (implicity True)` or `system.upgrade: (implicitly True)`. Or `apache.enable_site: example.com`.
+
+The first approach complicates things when detecting actual sub-commands (below). Script Tease supports both of these approaches.
+
+Fourth: The command also expects a sub-command. In some cases, the sub-command may be implicit, like `pip install`. In other cases, a number of sub-commands may be pre-defined, but ad hoc sub-commands should also be supported as with Django commands.
+
+Fifth: Builds upon the third and fourth conditions where the commands have lots of options, some of which may be defined at runtime. Postgres and MySQL may use be presented as informal sub-commands, but there are lots of options and challenges in building the final command. Django management commands have a number of standard options, specific options, and must also support ad hoc commands.
+
+## Terms and Definitions
+
+command
+:   When used in Script Tease documentation, this is a command instance which contains the properties and parameters for a command line statement.
+
+statement
+:   A specific statement (string) to be executed. A *statement* is contained within a *command*.
+
+## License

-
-The `tease` command may be used to parse a steps file, providing additional utilities for working with commands.
-
-## Getting Help
-
-Use `tease -h` to get started. There are three (3) sub-commands: [docs](#the-docs-sub-command), [inventory](#the-inventory-sub-command), and [script](#the-script-sub-command).
-
-```text
-usage: tease [-h] [-v] [--version] docs, inventory, script ...
-
-positional arguments:
-  docs, inventory, script
-                        Commands
-    docs                Output documentation instead of code.
-    inventory (inv)     Copy an inventory item to a local directory.
-    script              Output the commands.
-
-optional arguments:
-  -h, --help            show this help message and exit
-  -v                    Show version number and exit.
-  --version             Show verbose version information and exit.
-
-NOTES
-
-    This command is used to parse configuration files and output the commands.
-
-```
-
-## The Docs Sub-Command
-
-A nice benefit of using configuration for commands is that the information may be used to output documentation. This allows the automatic creation of an install guide or tutorial using exactly the same commands that would be used for the actual work.
-
-Additionally, Script Tease provides the [explain](commands/messages.md#explain) and [screenshot](commands/messages.md#screenshot) commands that help provide extra content for documentary output.
-
-```text
-usage: tease docs [-h] [-o= {html,md,plain,rst}] [-C= VARIABLES] [-i= STEPS_FILE] [-O= OPTIONS] [-P= {centos,ubuntu}]
-                  [-T= TEMPLATE_LOCATIONS] [-w= OUTPUT_FILE] [-V= VARIABLES_FILE] [-D] [-p]
-
-optional arguments:
-  -h, --help            show this help message and exit
-  -o= {html,md,plain,rst}, --output-format= {html,md,plain,rst}
-                        The output format; HTML, Markdown, plain text, or ReStructuredText.
-  -C= VARIABLES, --context= VARIABLES
-                        Context variables for use in pre-parsing the config and templates. In the form of: name:value
-  -i= STEPS_FILE, --input-file= STEPS_FILE
-                        The path to the configuration file.
-  -O= OPTIONS, --option= OPTIONS
-                        Common command options in the form of: name:value
-  -P= {centos,ubuntu}, --profile= {centos,ubuntu}
-                        The OS profile to use.
-  -T= TEMPLATE_LOCATIONS, --template-path= TEMPLATE_LOCATIONS
-                        The location of template files that may be used with the template command.
-  -w= OUTPUT_FILE, --write= OUTPUT_FILE
-                        Write the output to disk.
-  -V= VARIABLES_FILE, --variables-file= VARIABLES_FILE
-                        Load variables from a file.
-  -D, --debug           Enable debug mode. Produces extra output.
-  -p                    Preview mode.
-
-```
-
-## The Inventory Sub-Command
-
-Script Tease ships with few pre-defined configurations that may be copied to a local directory.
-
-Use `tease inv ?` to list available inventory items.
-
-```text
-usage: tease inventory [-h] [-P= TO_PATH] [-D] [-p] name
-
-positional arguments:
-  name                  The name of the inventory item. Use ? to list available items.
-
-optional arguments:
-  -h, --help            show this help message and exit
-  -P= TO_PATH, --path= TO_PATH
-                        The path to where the item should be copied. Defaults to the current working directory.
-  -D, --debug           Enable debug mode. Produces extra output.
-  -p                    Preview mode.
-
-```
-
-!!! note "Road Map"
-    A future release will include support for multiple inventory locations that may be defined by the user.
-
-## The Script Sub-Command
-
-The `script` sub-command exports command configuration to actual Bash statements. Minimum usage is 
-
-```bash
-tease -i steps.ini
-```
-
-This will output the statements represented in the specified configuration file. There are quite a few other parameters.
-
-```text
-usage: tease script [-h] [-c] [-s] [-C= VARIABLES] [-i= STEPS_FILE] [-O= OPTIONS] [-P= {centos,ubuntu}] [-T= TEMPLATE_LOCATIONS]
-                    [-w= OUTPUT_FILE] [-V= VARIABLES_FILE] [-D] [-p]
-
-optional arguments:
-  -h, --help            show this help message and exit
-  -c, --color           Enable code highlighting for terminal output.
-  -s, --shebang         Add the shebang to the beginning of the output.
-  -C= VARIABLES, --context= VARIABLES
-                        Context variables for use in pre-parsing the config and templates. In the form of: name:value
-  -i= STEPS_FILE, --input-file= STEPS_FILE
-                        The path to the configuration file.
-  -O= OPTIONS, --option= OPTIONS
-                        Common command options in the form of: name:value
-  -P= {centos,ubuntu}, --profile= {centos,ubuntu}
-                        The OS profile to use.
-  -T= TEMPLATE_LOCATIONS, --template-path= TEMPLATE_LOCATIONS
-                        The location of template files that may be used with the template command.
-  -w= OUTPUT_FILE, --write= OUTPUT_FILE
-                        Write the output to disk.
-  -V= VARIABLES_FILE, --variables-file= VARIABLES_FILE
-                        Load variables from a file.
-  -D, --debug           Enable debug mode. Produces extra output.
-  -p                    Preview mode.
-
-```
-
-### Context Variables May be Provided on the Command Line
-
-To supply context variables on the command line:
-
-```bash
-tease -C domain_name:example.com -C domain_tld:example_com
-```
-
-!!! important
-    Variables provided on the command will always override those provided in a file.
-
-### Loading Context Variables from a File
-
-Context variables may be loaded from a file:
-
-```ini
-[domain_name]
-value = example.com
- 
-[domain_tld] 
-value = example_com
-```
-
-The variables above are available as template variables in a steps file. 
-
-For example, ``{{ domain_name }}`` becomes ``example.com``.
-
-To load the variables file, use the `-V` switch:
-
-```bash
-tease -i steps.ini -V variables.ini
-
-```
-
-### Setting Common Options for All Commands
-
-Rather than include a common parameter in the configuration file, it is possible to specify a common option on the command line.
-
-```bash
-tease -O sudo:yes
-
-```
-
-### The Difference Between Variables and Options
-
-Variables are used to pre-process configuration files as templates, while common options are passed to *all* command instances.

-# Use Script Tease With Common Kit
-
-Since the focus of Script Tease is to convert plain text instructions into valid command line statements, it does *not* provide support for executing those statements either locally or remotely. However, the shell component of [python-commonkit](https://docs.develmaycare.com/en/python-commonkit/stable/components/#module-commonkit.shell) *does* provide support for executing commands in local POSIX environments.
-
-Here is an example of how to use these packages together:
-
-```python
-from commonkit.shell import Command
-from scripttease.exceptions import InvalidInput
-from scripttease.lib.factories import command_factory
-from scripttease.lib.loaders import INILoader
-
-def execute(step):
-    command = Command(

-# Python Script Tease
-
-## Overview
-
-Script Tease is a library and command line tool for generating Bash commands programmatically and (especially) using configuration files.
-
-The primary focus (and limit) is to convert plain text instructions (in INI or YAML format) into valid command line statements for a given platform. It does *not* provide support for executing those statements.
-
-!!! warning
-    YAML support is currently untested.
-
-## Concepts
-
-### Command Generation
-
-Script Tease may be used in three (3) ways:
-
-1. Using the library to programmatically define commands and export them as command line statements. 
-2. Using the `tease` command to generate commands from a configuration file. See [steps file](topics/steps-file.md).
-3. Using the command file format and library to create a custom implementation.
-
-This documentation focuses on the second method, but the [developer docs](./reference) may be used to guide custom implementations for 1 and 3 above.
-
-### Self-Documenting
-
-The format of INI and YAML files is self-documenting. The command comment is this section (INI) or start of a list item (YAML). This ensures that all commands have a basic description of their purpose or intent.
-
-```ini
-[install apache]
-install: apache2
-
-```
-
-```yaml
-- install apache
-  install: apache2
-
-```
-
-### Representing Commands
-
-All commands are represented by simple, Python functions. These functions are responsible for accepting the arguments provided (usually by a command loader) and converting them into a common `Command` instance. This instance is then capable of generating a finished statement that may be used on the command line.
-
-#### Profiles
-
-Profiles contain command functions that are specific to an operating system. Not all operating systems support the same commands.
-
-!!! note
-    At present, the only defined operating system profiles are for Cent OS and Ubuntu.
-
-Profiles import and appropriate all other available commands.
-
-## Terms and Definitions
-
-command
-:    When used in Script Tease documentation, this is a command instance which contains the properties and parameters for assembling a command line statement.
-
-profile
-:    A collection of commands that work for a specific operating system profile.
-
-statement
-:    A specific statement (string) to be executed. A *statement* is generated from a *command*.
-
-## License
-
-Python Script Tease is released under the BSD 3 clause license.

-# Itemized Commands
-
-It is sometimes useful to create a single command entry that does the same thing with different input. Script Tease facilitates this with the "itemized" command.
-
-```ini
-[install common utilities]
-install: $item
-items: curl, git, lftp, wget
-```
-
-In the example above, statements will be generated to install each of the packages named in `items`.
-
-!!! note
-    Content commands (`explain` and `screenshot`) and Template commands cannot be itemized.

-# Templates
-
-Script Tease supports processing of template files using Jinja2.
-
-## Location of Templates
-
-By default, the location of template files are reckoned as relative to the steps file.
-
-```text
-package_name/
-|-- steps.ini
-|-- templates
-|   `-- httpd.conf
-```
-
-Upon loading the `steps.ini` file, any reference to a template file is assumed to be in the `templates/` directory in the same location.
-
-```ini
-[create the apache config]
-template: httpd.conf /etc/apache2/sites-available/example.app.conf
-
-```
-
-!!! tip
-    The `-T` switch of the `tease` command may be used to add template locations.
-
-## Template Context
-
-The context variables available to parse the template are:
-
-- Variables received on the command line are included in the context.
-- Variables loaded from a file.
-- Options passed to the loader from the command line are also included.
-
-Additionally, any unrecognized parameters specified in the command are included in the context. For example:
-
-```ini
-[create the httpd.conf file]
-template: httpd.conf /etc/apache/sites-available/example.com.conf
-ssl_enabled: yes
-```
-
-`ssl_enabled` is not a normal parameter for the template command, so it is included in the context.
