-.IR man (1)
-command to get more information.
-If the line starts `name(section) ...' you can do
-`man section name' to get the documentation for it.
-Try `whatis ed' and then you should do `man 1 ed' to get the manual.

-.I Whatis
-is actually just the
-.B \-f
-option to the
-.IR man (1)
-command.
+Normally \fIwhatis\fP checks in a standard location (/usr/man) for its
+database ``whatis''.  This can be changed by supplying a \fIpath\fP (a
+la the Bourne shell) with the \fB-M\fP flag.  This search path must be
+a colon (``:'') separated list of directories which \fIwhatis\fP will
+search for files named ``whatis''.  The path can also be set with the
+environmental variable \fIMANPATH\fP.
