Typographic Conventions

• This style is used for file and directory names.

• $	This style

  is used for user-issued shell commands.

•  This style is used for code the user is expected to enter.

• This font is used for `replaceable' text or variables. Replaceable text is text that describes something you're supposed to type, like a filename, in which the word `filename' is a placeholder for the actual filename.

• The following fonts are used to denote various programming constructs: class names (CCA `components'), interface names (CCA `ports'), and method names. Also variable names and ENVIRONMENT VARIABLES are marked up with special fonts.

• URLs are presented in square brackets after the name of the resource they describe in the print version of this Guide .

• Sometime we must break lines in computer output or program listings to fit the line widths available. In these cases, the break will be marked by a `\' character. In real computer output, you see a long continuous line rather than a broken one. For program listings, unless otherwise indicated, you can join up the broken lines. In shell commands, you can use the `\' and break the input over multiple lines.
