Subject: perl-module.eclass: Rename SRC_TEST to DIST_TEST in EAPI=6, default
 to "do parallel", add features

* The variable SRC_TEST used to allow some control over the testing phase (run
it, run tests parallelized, skip it). Named DIST_TEST in EAPI=6 now for
consistency.

* Add functionality for ebuild authors: even if the ebuild specifies that e.g.
tests should not be run or run single-threaded, allow in EAPI=6 to override
that from make.conf or package.env.

* Rewrite of the test phase for EAPI=6. Adds options to control test verbosity
and switch network tests (something that might or might not work depending on
upstream cooperativity).

+# @ECLASS-VARIABLE: DIST_TEST
+# @DESCRIPTION:
+# (EAPI=6) Variable that controls if tests are run in the test phase
+# at all, and if yes under which conditions. Defaults to "do parallel"
+# If neither "do" nor "parallel" is recognized, tests are skipped.
+# (In EAPI=5 the variable is called SRC_TEST, defaults to "skip", and
+# recognizes fewer options.)
+# The following space-separated keywords are recognized:
+#   do       : run tests
+#   parallel : run tests in parallel
+#   verbose  : increase test verbosity
+#   network  : do not try to disable network tests
+
+# @ECLASS-VARIABLE: DIST_TEST_OVERRIDE
+# @DESCRIPTION:
+# (EAPI=6) Variable that controls if tests are run in the test phase
+# at all, and if yes under which conditions. It is intended for use in
+# make.conf or the environment by ebuild authors during testing, and
+# accepts the same values as DIST_TEST. If set, it overrides DIST_TEST
+# completely. DO NOT USE THIS IN EBUILDS!

 # @FUNCTION: perl-module_src-test
 # @USAGE: perl-module_src_test()
 # @DESCRIPTION:
-# This code attempts to work out your threadingness from MAKEOPTS
-# and apply them to Test::Harness.
-#
-# If you want more verbose testing, set TEST_VERBOSE=1
-# in your bashrc | /etc/portage/make.conf | ENV
-#
-# or ebuild writers:
-# If you wish to enable default tests w/ 'make test' ,
-#
-#  SRC_TEST="do"
-#
-# If you wish to have threads run in parallel ( using the users makeopts )
-# all of the following have been tested to work.
-#
-#  SRC_TEST="do parallel"
-#  SRC_TEST="parallel"
-#  SRC_TEST="parallel do"
-#  SRC_TEST=parallel
-#
+# This code attempts to work out your threadingness and runs tests
+# according to the settings of DIST_TEST using Test::Harness.
