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. |
Constant Width |
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.
