		Helper class to handle INI-style files.
	</brief_description>
	<description>
		This helper class can be used to store [Variant] values on the filesystem using INI-style formatting. The stored values are identified by a section and a key:
		[codeblock]
		[section]
		some_key=42
		string_example="Hello World3D!"
		a_vector=Vector3(1, 0, 2)
		[/codeblock]
		The stored data can be saved to or parsed from a file, though ConfigFile objects can also be used directly without accessing the filesystem.
		The following example shows how to create a simple [ConfigFile] and save it on disc:
		[codeblocks]
		[gdscript]
		# Create new ConfigFile object.
		var config = ConfigFile.new()

		# Store some values.
		config.set_value("Player1", "player_name", "Steve")
		config.set_value("Player1", "best_score", 10)
		config.set_value("Player2", "player_name", "V3geta")
		config.set_value("Player2", "best_score", 9001)

		# Save it to a file (overwrite if already exists).
		config.save("user://scores.cfg")
		[/gdscript]
		[csharp]
		// Create new ConfigFile object.
		var config = new ConfigFile();

		// Store some values.
		config.SetValue("Player1", "player_name", "Steve");
		config.SetValue("Player1", "best_score", 10);
		config.SetValue("Player2", "player_name", "V3geta");
		config.SetValue("Player2", "best_score", 9001);

		// Save it to a file (overwrite if already exists).
		config.Save("user://scores.cfg");
		[/csharp]
		[/codeblocks]
		This example shows how the above file could be loaded:
		[codeblocks]
		[gdscript]
		var score_data = {}
		var config = ConfigFile.new()

		# Load data from a file.
		var err = config.load("user://scores.cfg")

		# If the file didn't load, ignore it.
		if err != OK:
		    return

		# Iterate over all sections.
		for player in config.get_sections():
		    # Fetch the data for each section.
		    var player_name = config.get_value(player, "player_name")
		    var player_score = config.get_value(player, "best_score")
		    score_data[player_name] = player_score
		[/gdscript]
		[csharp]
		var score_data = new Godot.Collections.Dictionary();
		var config = new ConfigFile();

		// Load data from a file.
		Error err = config.Load("user://scores.cfg");

		// If the file didn't load, ignore it.
		if (err != Error.Ok)
		{
		    return;
		}

		// Iterate over all sections.
		foreach (String player in config.GetSections())
		{
		    // Fetch the data for each section.
		    var player_name = (String)config.GetValue(player, "player_name");
		    var player_score = (int)config.GetValue(player, "best_score");
		    score_data[player_name] = player_score;
		}
		[/csharp]
		[/codeblocks]
		Any operation that mutates the ConfigFile such as [method set_value], [method clear], or [method erase_section], only changes what is loaded in memory. If you want to write the change to a file, you have to save the changes with [method save], [method save_encrypted], or [method save_encrypted_pass].
		Keep in mind that section and property names can't contain spaces. Anything after a space will be ignored on save and on load.
		ConfigFiles can also contain manually written comment lines starting with a semicolon ([code];[/code]). Those lines will be ignored when parsing the file. Note that comments will be lost when saving the ConfigFile. This can still be useful for dedicated server configuration files, which are typically never overwritten without explicit user action.
		[b]Note:[/b] The file extension given to a ConfigFile does not have any impact on its formatting or behavior. By convention, the [code].cfg[/code] extension is used here, but any other extension such as [code].ini[/code] is also valid. Since neither [code].cfg[/code] nor [code].ini[/code] are standardized, Godot's ConfigFile formatting may differ from files written by other programs.

		</method>
		<method name="get_section_keys" qualifiers="const">
			<return type="PackedStringArray" />
			<param index="0" name="section" type="String" />
			<description>
				Returns an array of all defined key identifiers in the specified section. Raises an error and returns an empty array if the section does not exist.
			</description>
