17. Conditionally Visible Text

The conditional commands allow you to use different text for different output formats, or for general conditions that you define. For example, you can use them to specify different text for the printed manual and the Info output.

The conditional commands comprise the following categories.

• Commands specific to an output format (Info, TeX, HTML, …).
• Commands specific to any output format other than a given one (not Info, not TeX, …).
• `Raw' formatter text for any output format, passed straight through with no interpretation of @-commands.
• Format-independent variable substitutions, and testing if a variable is set or clear.
