59 +.
42 60 The online Reference Manual page directories are conventionally located in
43 -\fB/usr/share/man\fR. The nroff sources are located in the
44 -\fB/usr/share/man/man\fR* directories. The \fBSGML\fR sources are located in
45 -the \fB/usr/share/man/sman\fR* directories. Each directory corresponds to a
61 +.Pa /usr/share/man .
62 +Each directory corresponds to a
46 63 section of the manual. Since these directories are optionally installed, they
47 -might not reside on your host. You might have to mount \fB/usr/share/man\fR
64 +might not reside on your host. You might have to mount

50 -.LP
51 -If there are preformatted, up-to-date versions in the corresponding \fBcat\fR*
52 -or \fBfmt\fR* directories, \fBman\fR simply displays or prints those versions.
53 -If the preformatted version of interest is out of date or missing, \fBman\fR
54 -reformats it prior to display and stores the preformatted version if \fBcat\fR*
55 -or \fBfmt\fR* is writable. The \fBwindex\fR database is not updated. See
56 -\fBcatman\fR(1M). If directories for the preformatted versions are not
57 -provided, \fBman\fR reformats a page whenever it is requested. \fBman\fR uses a
58 -temporary file to store the formatted text during display.
59 -.sp
60 -.LP
61 -If the standard output is not a terminal, or if the `\fB-\fR' flag is given,
