|
|
.Nm

|
|
.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.
|

.Sh ENVIRONMENT

|
|
The default list of acronym databases may be overridden by setting the
|
|
environment variable
|
|
.Ev ACRONYMDB
|
|
to the name of one or more space-separated file names of
|
|
acronym databases.
