+# The SLOT variable is used to tell Portage if it's OK to keep multiple
+# versions of the same package installed at the same time. For example,
+# if we have a libfoo-1.2.2 and libfoo-1.3.2 (which is not compatible
+# with 1.2.2), it would be optimal to instruct Portage to not remove
+# libfoo-1.2.2 if we decide to upgrade to libfoo-1.3.2. To do this,
+# we specify SLOT="1.2" in libfoo-1.2.2 and SLOT="1.3" in libfoo-1.3.2.
+# emerge clean understands SLOTs, and will keep the most recent version
+# of each SLOT and remove everything else.
+# Note that normal applications should use SLOT="0" if possible, since
+# there should only be exactly one version installed at a time.
+# DO NOT USE SLOT=""! This tells Portage to disable SLOTs for this package.

+
+# Using KEYWORDS, we can record masking information *inside* an ebuild
+# instead of relying on an external package.mask file. Right now, you
+# should set the KEYWORDS variable for every ebuild so that it contains
+# the names of all the architectures with which the ebuild works. We have
+# 4 official architecture names right now: "x86", "ppc", "sparc" and
+# "sparc64". So, if you've confirmed that your ebuild works on x86 and ppc,
+# you'd specify: KEYWORDS="x86"
+# For packages that are platform-independant (like Java, PHP or Perl
+# applications) specify KEYWORDS="*".
