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.

+# @ECLASS:			wxwidgets.eclass
+# @MAINTAINER:
+#  wxwidgets@gentoo.org
+# @BLURB:			Manages build configuration for wxGTK-using packages.
+# @DESCRIPTION:
+#  This eclass gives ebuilds the ability to build against a specific wxGTK
+#  SLOT and profile without interfering with the system configuration.  Any
+#  ebuild with a x11-libs/wxGTK dependency must use this eclass.
+#
+#  There are two ways to do it:
+#
+#    - set WX_GTK_VER before inheriting the eclass
+#    - set WX_GTK_VER and call need-wxwidgets from a phase function
+#
+#  (where WX_GTK_VER is the SLOT you want)
+#
+#  If your package has optional support for wxGTK (ie. by a USE flag) then
+#  you should use need-wxwidgets.  This is important because some packages
+#  will force-enable wxGTK if they find WX_CONFIG set in the environment.
+#
+# @CODE
+#      inherit wxwidgets
+#
+#      IUSE="X wxwidgets"
+#      DEPEND="wxwidgets? ( x11-libs/wxGTK:2.8[X?] )"
+#
+#      src_configure() {
+#          if use wxwidgets; then 
+#              WX_GTK_VER="2.8"
+#              if use X; then
+#                  need-wxwidgets unicode
+#              else
+#                  need-wxwidgets base-unicode
+#              fi
+#          fi
+#          econf --with-wx-config="${WX_CONFIG}"
+#      }
+# @CODE
+#
+# That's about as complicated as it gets.  99% of ebuilds can get away with:
+#
+# @CODE
+#      inherit wxwidgets
+#      DEPEND="wxwidgets? ( x11-libs/wxGTK:2.8[X] )
+#      ...
+#      WX_GTK_VER=2.8 need-wxwidgets unicode
+# @CODE
+#
+# Note: unless you know your package works with wxbase (which is very
+# doubtful), always depend on wxGTK[X].
+
+inherit eutils multilib
+
+# We do this in global scope so ebuilds can get sane defaults just by
+# inheriting.
