.Sh SYNOPSIS
.Nm
.Op Fl f Ar dbfile
.Op Fl o
.Op Ar is
.Ar term ...
.Sh DESCRIPTION
The
.Nm
utility looks up the meaning of one or more
.Ar term
operands specified on the command line.
.Pp
.Ar term
will first be searched for as an acronym in the acronym databases,
which are expected to be in the format
.Dq acronym[tab]meaning .
If no match has been found,
.Nm
will check to see if the term is known by
.Xr whatis 1 ,
.Xr pkg_info 1 ,
or, when called from within a pkgsrc package directory,
pkgsrc's internal help facility,
.Dq make help topic=XXX .
.Pp
The optional
.Ar is
operand will be ignored, allowing the
fairly natural
.Dq wtf is WTF
usage.
.Pp
The following option is available:
.Bl -tag -width flag
.It Fl f Ar dbfile
Overrides the default list of acronym databases, bypassing the value of the
.Ev ACRONYMDB
variable.
Unlike this variable the
.Fl f
option only accepts one file name as an argument,
but it may be given multiple times to specify more than one file to use.
.It Fl o
Include acronyms that could be considered offensive to some.
Please consult
.Xr fortune 6
for more information about the
.Fl o
flag.
