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.

+# @BLURB: An eclass for installing Ruby packages with proper support for multiple Ruby slots.
+# @DESCRIPTION:
+# The Ruby eclass is designed to allow an easier installation of Ruby packages
+# and their incorporation into the Gentoo Linux system.
+#
+# Currently available targets are:
+#  * ruby18 - Ruby (MRI) 1.8.x
+#  * ruby19 - Ruby (MRI) 1.9.x
+#  * ruby20 - Ruby (MRI) 2.0.x
+#  * ruby21 - Ruby (MRI) 2.1.x
+#  * ruby22 - Ruby (MRI) 2.2.x
+#  * ree18  - Ruby Enterprise Edition 1.8.x
+#  * jruby  - JRuby
+#  * rbx    - Rubinius
+#
+# This eclass does not define the implementation of the configure,
+# compile, test, or install phases. Instead, the default phases are
+# used.  Specific implementations of these phases can be provided in
+# the ebuild either to be run for each Ruby implementation, or for all
+# Ruby implementations, as follows:
+#
+#  * each_ruby_configure
+#  * all_ruby_configure
+
+# @ECLASS-VARIABLE: USE_RUBY
+# @DEFAULT_UNSET
+# @REQUIRED
+# @DESCRIPTION:
+# This variable contains a space separated list of targets (see above) a package
+# is compatible to. It must be set before the `inherit' call. There is no
+# default. All ebuilds are expected to set this variable.
+
+# @ECLASS-VARIABLE: RUBY_PATCHES
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# A String or Array of filenames of patches to apply to all implementations.
+
+# @ECLASS-VARIABLE: RUBY_OPTIONAL
+# @DESCRIPTION:
+# Set the value to "yes" to make the dependency on a Ruby interpreter
+# optional and then ruby_implementations_depend() to help populate
+# DEPEND and RDEPEND.
+
+# @ECLASS-VARIABLE: RUBY_S
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# If defined this variable determines the source directory name after
+# unpacking. This defaults to the name of the package. Note that this
+# variable supports a wildcard mechanism to help with github tarballs
+# that contain the commit hash as part of the directory name.
+
+# @ECLASS-VARIABLE: RUBY_QA_ALLOWED_LIBS
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# If defined this variable contains a whitelist of shared objects that
+# are allowed to exist even if they don't link to libruby. This avoids
+# the QA check that makes this mandatory. This is most likely not what
+# you are looking for if you get the related "Missing links" QA warning,
+# since the proper fix is almost always to make sure the shared object
+# is linked against libruby. There are cases were this is not the case
+# and the shared object is generic code to be used in some other way
+# (e.g. selenium's firefox driver extension). When set this argument is
+# passed to "grep -E" to remove reporting of these shared objects.

+# This is simply a replacement for the testrb command that load the test
+# files and execute them, with test-unit 2.x. This actually requires
+# either an old test-unit-2 version or 2.5.1-r1 or later, as they remove
+# their script and we installed a broken wrapper for a while.
+# This also respects TEST_VERBOSE and NOCOLOR environment variables.
