8     # you have problems, suggestions or questions.
9     # @BLURB: Eclass to provide Prefix functionality
10     # @DESCRIPTION:
11     # Gentoo Prefix allows users to install into a self defined offset
12     # located somewhere in the filesystem. Prefix ebuilds require
13     # additional functions and variables which are defined by this eclass.
14    
15     # @ECLASS-VARIABLE: EPREFIX
16     # @DESCRIPTION:
17     # The offset prefix of a Gentoo Prefix installation. When Gentoo Prefix
18     # is not used, ${EPREFIX} should be "". Prefix Portage sets EPREFIX,
19     # hence this eclass has nothing to do here in that case.
20     # Note that setting EPREFIX in the environment with Prefix Portage sets
21     # Portage into cross-prefix mode.
22     if [[ ! ${EPREFIX+set} ]]; then
23     export EPREFIX=''

31     # dies if no arguments are given, a file does not exist, or changing a
32     # file failed.
