+short_description: Manage Ordnance configuration sections
+description:
+  - Ordnance router configurations use a simple block indent file syntax
+    for segmenting configuration into sections.  This module provides
+    an implementation for working with these configuration sections in
+    a deterministic way.
+options:
+  commands:
+    description:
+      - The ordered set of commands that should be configured in the
+        section.  The commands must be the exact same commands as found
+        in the device running-config.  Be sure to note the configuration
+        command syntax as some commands are automatically modified by the
+        device config parser.
+    required: false
+    default: null
+    aliases: ['commands']
+  parents:
+    description:
+      - The ordered set of parents that uniquely identify the section
+        the commands should be checked against.  If the parents argument
+        is omitted, the commands are checked against the set of top
+        level or global commands.
+    required: false
+    default: null
+  src:
+    description:
+      - Specifies the source path to the file that contains the configuration
+        or configuration template to load.  The path to the source file can
+        either be the full path on the Ansible control host or a relative
+        path from the playbook or role root directory.  This argument is mutually
+        exclusive with I(lines).
+    required: false
+    default: null
+  before:
+    description:
+      - The ordered set of commands to push on to the command stack if
+        a change needs to be made.  This allows the playbook designer
+        the opportunity to perform configuration commands prior to pushing
+        any changes without affecting how the set of commands are matched
+        against the system.
+    required: false
+    default: null
+  after:
+    description:
+      - The ordered set of commands to append to the end of the command
+        stack if a change needs to be made.  Just like with I(before) this
+        allows the playbook designer to append a set of commands to be
+        executed after the command set.
+    required: false
+    default: null
+  match:
+    description:
+      - Instructs the module on the way to perform the matching of
+        the set of commands against the current device config.  If
+        match is set to I(line), commands are matched line by line.  If
+        match is set to I(strict), command lines are matched with respect
+        to position.  If match is set to I(exact), command lines
+        must be an equal match.  Finally, if match is set to I(none), the
+        module will not attempt to compare the source configuration with
+        the running configuration on the remote device.
+    required: false
+    default: line
+    choices: ['line', 'strict', 'exact', 'none']
+  replace:
+    description:
+      - Instructs the module on the way to perform the configuration
+        on the device.  If the replace argument is set to I(line) then
+        the modified lines are pushed to the device in configuration
+        mode.  If the replace argument is set to I(block) then the entire
+        command block is pushed to the device in configuration mode if any
+        line is not correct.
+    required: false
+    default: line
+    choices: ['line', 'block']
+  multiline_delimiter:
+    description:
+      - This arugment is used when pushing a multiline configuration
+        element to the Ordnance router.  It specifies the character to use
+        as the delimiting character.  This only applies to the
+        configuration action
+    required: false
+    default: "@"
+  backup:
+    description:
+      - This argument will cause the module to create a full backup of
+        the current C(running-config) from the remote device before any
+        changes are made.  The backup file is written to the C(backup)
+        folder in the playbook root directory.  If the directory does not
+        exist, it is created.
+    required: false
+    default: no
+    choices: ['yes', 'no']
+  config:
+    description:
+      - The C(config) argument allows the playbook designer to supply
+        the base configuration to be used to validate configuration
+        changes necessary.  If this argument is provided, the module
+        will not download the running-config from the remote node.
+    required: false
+    default: null
+  defaults:
+    description:
+      - This argument specifies whether or not to collect all defaults
+        when getting the remote device running config.  When enabled,
+        the module will get the current config by issuing the command
+        C(show running-config all).
+    required: false
+    default: no
+    choices: ['yes', 'no']
+  save:
+    description:
+      - The C(save) argument instructs the module to save the running-
+        config to the startup-config at the conclusion of the module
+        running.  If check mode is specified, this argument is ignored.
