# This file collects definitions that are useful when using pkgsrc as an
# unprivileged (non-root) user. It is included automatically by the
# pkgsrc infrastructure.
#
# The following variables may be set by the pkgsrc user in mk.conf:
#
# UNPRIVILEGED		: YesNo (default: undefined)
#	If set to 'yes', enable unprivileged builds.
#
# UNPRIVILEGED_GROUP	: Groupname (default: the current group)
#	Specifies the group name (or gid) that will be used to install
#	files.
#
# UNPRIVILEGED_USER	: Username (default: the current user)
#	Specifies the user name (or uid) that will be used to install
#	files.
