.Sh DESCRIPTION
.Nm
is used for displaying information about packages.
.Sh OPTIONS
The following options are supported by
.Nm :
.Bl -tag -width evaluate
.It Fl a , Cm --all
Match all packages from the database
.It Fl C , Cm --case-sensitive
Make the standard or the regular expression
.Fl ( x )
matching against
.Ar pkg-name
in pattern case sensitive.
.It Fl e , Cm --evaluate
Match packages using the given
.Ar evaluation-condition .
See
.Sx EVALUATION FORMAT
for details.
.It Fl F Ar pkg-file , Cm --file Ar pkg-file
Display information only for the package file
.Ar pkg-name .
.It Fl i , Cm --case-insensitive
Make the standard or regular expression
.Fl ( x )
matching against
.Ar pkg-name
in pattern case insensitive.
This is the default, unless modified by setting
.Ev CASE_SENSITIVE_MATCH
to true in
.Pa pkg.conf .
.It Fl g , Cm --glob
Treat
.Ao pattern Ac
as a glob pattern.
.It Fl x , Cm --regex
Treat
.Ao pattern Ac
as a regular expression according to the "modern" or "extended" syntax
of
.Xr re_format 7 .
.El
.Sh QUERY FORMAT
There are two types of keywords for the query format: the multiline and the
normal one.
Only one type of multiline pattern is accepted for a given query.

.Sh EVALUATION FORMAT
Packages can be selected by using expressions comparing
.Ar Variables
(see below) to string or integer values.
The mode of comparison is specified by the
.Ar Operator
(also listed below).
Expressions can be combined using && (for and) and || (for or).
Parentheses can be used for grouping in the usual manner.
.Pp
String values are either any text not containing whitespace (possibly
followed by but not including whitespace) or any text enclosed in single or
double quotes.
