+/**
+ * @file testscripts.h Defines classes for reading a configuration file
+ *
+ * @note Configuration File Format:
+ * 
+ * [Defaults]
+ * defaults= another_config_file.txt
+ *
+ * [SectionName]
+ * variable= value
+ * variable2= value2
+ * variable= value3
+ *
+ * [SectionName2]
+ * variable= value
+ *
+ * endscript
+ *
+ * 
+ * @note Explanation:
+ *
+ * A configuration file is made up of a number of "sections", each of which can contain a number of "items" (name, value combination).
+ * 
+ * "Sections" must have a name and be surrounded by square backets, e.g.:
+ *
+ *      [SectionName]
+ *
+ *
+ * Each "item" consists of consists of a name, followed by an equals sign, followed by blank space, followed by the value to assign to that variable.
+ * 
+ * The value can be of any length, contain whitespace and span multiple lines. The value ends when the next item or section is found. E.g:
+ * 
+ * Simple Item:
+ *
+ *      variable= value
+ *
+ * Two items on one line:
+ *
+ *      variable= value variable2= value2
+ *
+ * Multi-line item:
+ *
+ *      variable= This variable
+ *      spans multiple
+ *      lines
+ *
+ * 
+ * @note Parsing stops at End-Of-File or if the tag "endscript" (without the quotes) appears in the file.
+ *
+ * @note A section may take some default values from another section or config file
+ *
+ * To specify default values for all sections, add a section at the start of the config file called [Defaults], e.g.:
+ *
+ *      [Defaults]
+ *      sc= +447785016005
+ *
+ * To read default values from another config file, add an item with name "defaults" and value is the name of the file. E.g.:
+ *
+ *      defaults= another_config_file.txt
