The documentation uses the following typographic conventions:
|Bold||is used for directories, filenames, directives, qualifiers, and options. All terms show in bold are typed literally.|
|Italic||is used to show generic qualifiers and options. These should be replaced with user-supplied values. Italic is also used to highlight comments in examples.|
||is used in examples to show the contents of files and to show directives included in files.|
|Brackets ([ ])||surround optional elements in a description of syntax. The brackets themselves should not be typed.|
|Pipe ( | )||is used in syntax descriptions to separate items for which only one alternative may be chosen at a time.|
In this documentation, capitalization was used only to improve readability. Directives, qualifiers, and options are case-insensitive.
