+author: "Lindsay Hill (@LindsayHill)"
+short_description: Manage Extreme Networks NOS configuration sections
+description:
+  - Extreme NOS configurations use a simple block indent file syntax
+    for segmenting configuration into sections. This module provides
+    an implementation for working with NOS configuration sections in
+    a deterministic way.
+notes:
+  - Tested against NOS 7.2.0
+options:
+  lines:
+    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.
+    default: null
+    aliases: ['commands']
+  parents:
+    description:
+      - The ordered set of parents that uniquely identify the section or hierarchy
+        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.
+    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), I(parents).
+    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.
+    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.
+    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.
+    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.
+    default: line
+    choices: ['line', 'block']
+  multiline_delimiter:
+    description:
+      - This argument is used when pushing a multiline configuration
+        element to the NOS device. It specifies the character to use
+        as the delimiting character. This only applies to the
+        configuration action.
+    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.
+    default: no
+    type: bool
+  running_config:
+    description:
+      - The module, by default, will connect to the remote device and
+        retrieve the current running-config to use as a base for comparing
+        against the contents of source. There are times when it is not
+        desirable to have the task get the current running-config for
+        every task in a playbook. The I(running_config) argument allows the
+        implementer to pass in the configuration to use as the base
+        config for comparison.
+    default: null
+    aliases: ['config']
+  diff_against:
+    description:
+      - When using the C(ansible-playbook --diff) command line argument
+        the module can generate diffs against different sources.
+      - When this option is configured as I(intended), the module will
+        return the diff of the running-config against the configuration
+        provided in the C(intended_config) argument.
+      - When this option is configured as I(running), the module will
+        return the before and after diff of the running-config with respect
+        to any changes made to the device configuration.
+    choices: ['running', 'intended']
+  diff_ignore_lines:
+    description:
+      - Use this argument to specify one or more lines that should be
+        ignored during the diff. This is used for lines in the configuration
+        that are automatically updated by the system. This argument takes
+        a list of regular expressions or exact line matches.
+  intended_config:
+    description:
+      - The C(intended_config) provides the master configuration that
+        the node should conform to and is used to check the final
+        running-config against. This argument will not modify any settings
+        on the remote device and is strictly used to check the compliance
+        of the current device's configuration against. When specifying this
+        argument, the task should also modify the C(diff_against) value and
+        set it to I(intended).
