+[BUILD]
+# If the profile is pulled in from an overlay you will need to specify it.
+# Well known locations of the "src/overlays, /usr/local/portage" etc will 
+# be searched for the overlay
+overlay: overlay-x86-generic
+
+# The profile to use for building this target
+# ALL is a reserved target that builds all specfiles recursively beneath
+# e.g:
+# profile: x86-generic/base
+profile: x86-generic/dev
+
+# portagechannel speficies which version of the upstream portage is being built
+#   "stable" is the current stable version
+#   "unstable" is the next version of portage we are stablizing to
+#   "bleedingedge" is upto the minute upstream portage
+# e.g: 
+# portagechannel: stable
+portagechannel: stable
+
+# prebuilt mirror hosts prebuilts for stage4/chroot and per profile prebuilts
+# e.g:
+# prebuiltmirror:http://build.chromium.org/mirror/chromiumos/stage4mirror 
+prebuiltmirror:http://build.chromium.org/mirror/chromiumos/stage4mirror 
+
+# stage4 is the Portage Stage3 + any additions deps (hard-host-deps etc)
+#  "latest" tries to fetch the "latest" from the prebuilt mirror (default)  
+#            -- This is pulled in from the current portagechannel i.e stable
+#  "nofetch" will prevent fetching stage4 and attempt to compile a stage4
+#            If nofetch is specified a stage3 and portage are required
+#  "version" This will attempt to download a particular prebuilt version 
+#           - Version is specfied as s<stage3ver>-p<portagever>
+# e.g:
+# stage4: stage4-s20100309-p20100310
+stage4: latest
+
+# stage3 is the pristine stage3 to use to build your stage4/chroot.
+# This is ignored if stage4 is latest
+#   "latest" fetches the latest version of upstream stage3
+#   "version" pulls in the specified version of stage3
+# e.g:
+# stage3: 20100309
+stage3: latest
+
+# portage is the upstream portage version to use to build your stage4/chroot.
+#   "latest" fetches the latest version of upstream portage
+#   "version" pulls in the specified version of portage
+# e.g:
+# portage: 20100310
