This guide uses the standard UNIX® convention for referring to entries in IRIX documentation. The entry name is followed by the section number in parentheses. For example, rcp(1C) refers to the rcp online reference page. In most cases, when you find mention of a reference page in this guide, you can click on the entry and the reference page is displayed.
