A constant-width font is used for displaying the names of files and directories.
We recommend that you read a typeset version of this document rather than the plain text version. In the typeset version, the names of files and directories are displayed in a constant-width font.
Components of filenames that vary are represented by a description of the contents enclosed in "<" and ">" characters, <thus>. Electronic mail addresses are also enclosed in "<" and ">" but are shown in the usual typeface.
Optional components of filenames are enclosed in "[" and "]" characters and may be combined with the "<" and ">" convention. For example, if a file existed which could be either be found either with or without an extension, it might be represented by <filename>[.<extension>].
Variable substrings of directory names and filenames are indicated by "*".
