.Sh SYNOPSIS
.Nm
.Op Fl Ldq
.Sh DESCRIPTION
The

for the first of:
.Bl -dash -compact
.It
.Pa pathname/man
.It
.Pa pathname/MAN
.It
If pathname ends with /bin:
.Pa pathname/../man
.El
Note: Special logic exists to make
.Pa /bin
and
.Pa /usr/bin
look in
.Pa /usr/share/man
for manual files.
.It
The configuration files listed in the
.Sx FILES
section for
.Va MANPATH
entries.
.El
The information from these locations is then concatenated together.
