The standard strings file format consists of one or more key-value pairs along with optional comments. The key and value in a given pair are strings of text enclosed in double quotation marks, separated by an equal sign, and terminated by a semicolon. (You can also use a property list format for strings files. In such a case, the top-level node is a dictionary and each key-value pair of that dictionary is a string entry.) Although the inclusion of comments is optional, they do provide a useful way to communicate contextual information to the translator about how each string is used.
