Monospaced font is used for any text that appears on the computer screen, commands that the user inputs, filenames, functions, and examples. For example:

cd /var/lib/rhpki-ca/

Italics are used for emphasis, variables, book titles, glossary terms, and when a phrase is first used. For example:

This control depends on the access permissions the super user has set for the user.

Square brackets ([]) enclose commands that are optional. For example:

PrettyPrintCert input_file[output_file]

input_file specifies the path to the file that contains the base-64 encoded certificate. output_file specifies the path to the file to write the certificate. This argument is optional; if an output file is not specified, the certificate information is written to the standard output.

A forward slash (/) is used to separate directories in a path. For example:

Almost all command-line utilities are in the /usr/bin directory.
