+short_description: Manage configuration sections on Brocade Ironware devices
+description:
+  - Brocade Ironware configurations use a simple block indent file syntax
+    for segmenting configuration into sections.  This module provides
+    an implementation for working with Ironware configuration sections in
+    a deterministic way.

+  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.
+    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']
+  update:
+    description:
+      - The I(update) argument controls how the configuration statements
+        are processed on the remote device.  Valid choices for the I(update)
+        argument are I(merge) and I(check).  When the argument is set to
+        I(merge), the configuration changes are merged with the current
+        device running configuration.  When the argument is set to I(check)
+        the configuration updates are determined but not actually configured
+        on the remote device.
+    required: false
+    default: merge
+    choices: ['merge', 'check']
+  commit:
+    description:
+      - This argument specifies the update method to use when applying the
+        configuration changes to the remote node.  If the value is set to
+        I(merge) the configuration updates are merged with the running-
+        config.  If the value is set to I(check), no changes are made to
+        the remote host.
+    required: false
+    default: merge
+    choices: ['merge', 'check']
+  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
+  save_when:
+    description:
+      - When changes are made to the device running-configuration, the
+        changes are not copied to non-volatile storage by default.  Using
+        this argument will change that before.  If the argument is set to
+        I(always), then the running-config will always be copied to the
+        startup-config and the I(modified) flag will always be set to
+        True.  If the argument is set to I(modified), then the running-config
+        will only be copied to the startup-config if it has changed since
+        the last save to startup-config.  If the argument is set to
+        I(never), the running-config will never be copied to the
+        startup-config
+    required: false
+    default: never
+    choices: ['always', 'never', 'modified']
