proj/gentoo: Initial commit
This commit represents a new era for Gentoo: Storing the gentoo-x86 tree in Git, as converted from CVS. This commit is the start of the NEW history. Any historical data is intended to be grafted onto this point. Creation process: 1. Take final CVS checkout snapshot 2. Remove ALL ChangeLog* files 3. Transform all Manifests to thin 4. Remove empty Manifests 5. Convert all stale $Header$/$Id$ CVS keywords to non-expanded Git $Id$ 5.1. Do not touch files with -kb/-ko keyword flags. Signed-off-by: Robin H. Johnson <robbat2@gentoo.org> X-Thanks: Alec Warner <antarus@gentoo.org> - did the GSoC 2006 migration tests X-Thanks: Robin H. Johnson <robbat2@gentoo.org> - infra guy, herding this project X-Thanks: Nguyen Thai Ngoc Duy <pclouds@gentoo.org> - Former Gentoo developer, wrote Git features for the migration X-Thanks: Brian Harring <ferringb@gentoo.org> - wrote much python to improve cvs2svn X-Thanks: Rich Freeman <rich0@gentoo.org> - validation scripts X-Thanks: Patrick Lauer <patrick@gentoo.org> - Gentoo dev, running new 2014 work in migration X-Thanks: Michał Górny <mgorny@gentoo.org> - scripts, QA, nagging X-Thanks: All of other Gentoo developers - many ideas and lots of paint on the bikeshed

+# @ECLASS-VARIABLE: EGO_PN
+# @REQUIRED
+# @DESCRIPTION:
+# This is the import path for the go package(s). Please emerge dev-lang/go
+# and read "go help importpath" for syntax.
+#
+# Example:
+# @CODE
+# EGO_PN="github.com/user/package"
+# EGO_PN="github.com/user1/package1 github.com/user2/package2"
+# @CODE
+
+# @ECLASS-VARIABLE: EGO_SRC
+# @DESCRIPTION:
+# This is the Go upstream repository which will be copied to
+# ${WORKDIR}/${P}.
+# If it isn't set, it defaults to the first word of ${EGO_PN}.
+# This should be set if you are retrieving a repository that includes
+# multiple packages, e.g. golang.org/x/tools.
+#

+# @CODE
+# EGO_PN="github.com/user/repository/..."
+# EGO_SRC="github.com/user/repository"
+# @CODE
+
+# @ECLASS-VARIABLE: EGO_STORE_DIR

+# it.

+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# Set this variable to a custom umask. This is intended to be set by
+# users. By setting this to something like 002, it can make life easier
+# for people who do development as non-root (but are in the portage
+# group) and use FEATURES=userpriv.
