+# @BLURB: Eclass to provide Prefix functionality
+# @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.
+if [[ ! ${EPREFIX+set} ]]; then
+	export EPREFIX=''
+fi
+
+
+# @FUNCTION: eprefixify
+# @USAGE: <list of to be eprefixified files>
+# @DESCRIPTION:
+# replaces @GENTOO_PORTAGE_EPREFIX@ with ${EPREFIX} for the given files,
+# dies if no arguments are given, a file does not exist, or changing a
+# file failed.
