# @DESCRIPTION:
# Gentoo Prefix allows users to install into a self defined offset
# located somewhere in the filesystem.  Prefix ebuilds require
# additional functions and variables which are defined by this eclass.

# @ECLASS-VARIABLE: EPREFIX
# @DESCRIPTION:
# The offset prefix of a Gentoo Prefix installation.  When Gentoo Prefix
# is not used, ${EPREFIX} should be "".  Prefix Portage sets EPREFIX,
# hence this eclass has nothing to do here in that case.
# Note that setting EPREFIX in the environment with Prefix Portage sets
# Portage into cross-prefix mode.
