+"""
+Augeas implementation of the ParserNode interfaces.
+
+Augeas works internally by using XPATH notation. The following is a short example
+of how this all works internally, to better understand what's going on under the
+hood.
+
+A configuration file /etc/apache2/apache2.conf with the following content:
+
+    # First comment line
+    # Second comment line
+    WhateverDirective whatevervalue
+    <ABlock>
+        DirectiveInABlock dirvalue
+    </ABlock>
+    SomeDirective somedirectivevalue
+    <ABlock>
+        AnotherDirectiveInABlock dirvalue
+    </ABlock>
+    # Yet another comment
+
+
+Translates over to Augeas path notation (of immediate children), when calling
+for example: aug.match("/files/etc/apache2/apache2.conf/*")
+
+[
+    "/files/etc/apache2/apache2.conf/#comment[1]",
+    "/files/etc/apache2/apache2.conf/#comment[2]",
+    "/files/etc/apache2/apache2.conf/directive[1]",
+    "/files/etc/apache2/apache2.conf/ABlock[1]",
+    "/files/etc/apache2/apache2.conf/directive[2]",
+    "/files/etc/apache2/apache2.conf/ABlock[2]",
+    "/files/etc/apache2/apache2.conf/#comment[3]"
+]
+
+Regardless of directives name, its key in the Augeas tree is always "directive",
+with index where needed of course. Comments work similarly, while blocks
+have their own key in the Augeas XPATH notation.
+
+It's important to note that all of the unique keys have their own indices.
+
+Augeas paths are case sensitive, while Apache configuration is case insensitive.
+It looks like this:
+
+    <block>
+        directive value
+    </block>
+    <Block>
+        Directive Value
+    </Block>
+    <block>
+        directive value
+    </block>
+    <bLoCk>
+        DiReCtiVe VaLuE
+    </bLoCk>
+
+Translates over to:
+
+[
+    "/files/etc/apache2/apache2.conf/block[1]",
+    "/files/etc/apache2/apache2.conf/Block[1]",
+    "/files/etc/apache2/apache2.conf/block[2]",
+    "/files/etc/apache2/apache2.conf/bLoCk[1]",

+"""ParserNode interface for interacting with configuration tree.
+
+General description
+-------------------
+
+The ParserNode interfaces are designed to be able to contain all the parsing logic,
+while allowing their users to interact with the configuration tree in a Pythonic
+and well structured manner.
+
+The structure allows easy traversal of the tree of ParserNodes. Each ParserNode
+stores a reference to its ancestor and immediate children, allowing the user to
+traverse the tree using built in interface methods as well as accessing the interface
+properties directly.
+
+ParserNode interface implementation should stand between the actual underlying
+parser functionality and the business logic within Configurator code, interfacing
+with both. The ParserNode tree is a result of configuration parsing action.
+
+ParserNode tree will be in charge of maintaining the parser state and hence the
+abstract syntax tree (AST). Interactions between ParserNode tree and underlying
+parser should involve only parsing the configuration files to this structure, and
+writing it back to the filesystem - while preserving the format including whitespaces.
+
+For some implementations (Apache for example) it's important to keep track of and
+to use state information while parsing conditional blocks and directives. This
+allows the implementation to set a flag to parts of the parsed configuration
+structure as not being in effect in a case of unmatched conditional block. It's
+important to store these blocks in the tree as well in order to not to conduct
+destructive actions (failing to write back parts of the configuration) while writing
+the AST back to the filesystem.
+
+The ParserNode tree is in charge of maintaining the its own structure while every
+child node fetched with find - methods or by iterating its list of children can be
+changed in place. When making changes the affected nodes should be flagged as "dirty"
+in order for the parser implementation to figure out the parts of the configuration
+that need to be written back to disk during the save() operation.
+
+
+Metadata
+--------
+
+The metadata holds all the implementation specific attributes of the ParserNodes -
+things like the positional information related to the AST, file paths, whitespacing,
+and any other information relevant to the underlying parser engine.
+
+Access to the metadata should be handled by implementation specific methods, allowing
+the Configurator functionality to access the underlying information where needed.
+
+For some implementations the node can be initialized using the information carried
+in metadata alone. This is useful especially when populating the ParserNode tree
+while parsing the configuration.
+
+
+Apache implementation
+---------------------
+
+The Apache implementation of ParserNode interface requires some implementation
+specific functionalities that are not described by the interface itself.
+
+Initialization
+
+When the user of a ParserNode class is creating these objects, they must specify
+the parameters as described in the documentation for the __init__ methods below.
+When these objects are created internally, however, some parameters may not be
+needed because (possibly more detailed) information is included in the metadata
+parameter. In this case, implementations can deviate from the required parameters
+from __init__, however, they should still behave the same when metadata is not
+provided.
+
+For consistency internally, if an argument is provided directly in the ParserNode
+initialization parameters as well as within metadata it's recommended to establish
+clear behavior around this scenario within the implementation.
+
+Conditional blocks
+
+Apache configuration can have conditional blocks, for example: <IfModule ...>,
+resulting the directives and subblocks within it being either enabled or disabled.
+While find_* interface methods allow including the disabled parts of the configuration
+tree in searches a special care needs to be taken while parsing the structure in
+order to reflect the active state of configuration.
+
+Whitespaces
+
+Each ParserNode object is responsible of storing its prepending whitespace characters
+in order to be able to write the AST back to filesystem like it was, preserving the
+format, this applies for parameters of BlockNode and DirectiveNode as well.
+When parameters of ParserNode are changed, the pre-existing whitespaces in the
+parameter sequence are discarded, as the general reason for storing them is to
+maintain the ability to write the configuration back to filesystem exactly like
+it was. This loses its meaning when we have to change the directives or blocks
+parameters for other reasons.
+
+Searches and matching
+
+Apache configuration is largely case insensitive, so the Apache implementation of
+ParserNode interface needs to provide the user means to match block and directive
+names and parameters in case insensitive manner. This does not apply to everything
+however, for example the parameters of a conditional statement may be case sensitive.
+For this reason the internal representation of data should not ignore the case.

+    While for the most parts the usage and the child types are obvious, "include"-
+    and similar directives are an exception to this rule. This is because of the

+    configuration block to their place. While we could unroll the included nodes
+    to the parent tree, it remains important to keep the context of include nodes
+    separate in order to write back the original configuration as it was.
+
+    For parsers that require the implementation to keep track of the whitespacing,
+    it's responsibility of each ParserNode object itself to store its prepending
+    whitespaces in order to be able to reconstruct the complete configuration file
+    as it was when originally read from the disk.
