.Nm pkg_install.conf
.Nd configuration file for package installation tools
.Sh DESCRIPTION
The file
.Nm
contains system defaults for the package installation tools
as a list of variable-value pairs.
Each line has the format
.Ev VARIABLE=VALUE .
If the value consists of more than one line, each line is prefixed with
.Ev VARIABLE= .
.Pp
The current value of a variable can be checked by running
.Dl Ic pkg_admin config-var VARIABLE
