-.SH SYNOPSIS

-.SH DESCRIPTION
-.sp
-.LP
-The \fBapropos\fR utility displays the man page name, section number, and a
-short description for each man page whose \fBNAME\fR line contains
-\fIkeyword\fR. This information is contained in the \fB/usr/share/man/windex\fR
-database created by \fBcatman\fR(1M). If \fBcatman\fR(1M) was not run, or was
-run with the \fB-n\fR option, \fBapropos\fR fails. Each word is considered
-separately and the case of letters is ignored. Words which are part of other
-words are considered; for example, when looking for `compile', \fBapropos\fR
-finds all instances of `compiler' also.
-.sp
-.LP
-\fBapropos\fR is actually just the \fB-k\fR option to the \fBman\fR(1) command.
