+# @ECLASS: perl-virtual.eclass
+# @MAINTAINER:
+# perl@gentoo.org
+# @BLURB: Set up virtuals for perl modules more easily
+# @DESCRIPTION:
+# The perl-virtual.eclass sets all possible ebuild variables. It uses the
+# PM_PROVIDER array to set the any-of-many runtime dependencies.
+# @EXAMPLE:
+# An ebuild might look like this:
+#
+# @CODE
+#
+# PM_PROVIDER+=( "~dev-lang/perl-5.12.3" )
+# PM_PROVIDER+=( "5.10.1" )
+# inherit perl-virtual
+# KEYWORDS="~amd64 ~x86"
+# IUSE=""
+#
+# @CODE
+
+# @ECLASS-VARIABLE: PM_PROVIDER
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# The array should list the providers to be added to RDEPEND
+# with preference from highest to lowest.
+# If an element starts with "5", it is considered a ~dev-lang/perl version.
+# If PM_PROVIDER is not defined, RDEPEND isn't set.
+# ~perl-core/${PN#perl-}-${PV} is added at the end automatically.
