 		[EditorTranslationParserPlugin] is invoked when a file is being parsed to extract strings that require translation. To define the parsing and string extraction logic, override the [method _parse_file] method in script.
-		The return value should be an [Array] of [PackedStringArray]s, one for each extracted translatable string. Each entry should contain [code][msgid, msgctxt, msgid_plural, comment][/code], where all except [code]msgid[/code] are optional. Empty strings will be ignored.

 		The extracted strings will be written into a POT file selected by user under "POT Generation" in "Localization" tab in "Project Settings" menu.
 		Below shows an example of a custom parser that extracts strings from a CSV file to write into a POT.
