+# @ECLASS-VARIABLE: python_moduleroot
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# The current module root for python_domodule(). The path can be either
+# an absolute system path (it must start with a slash, and ${D} will be
+# prepended to it) or relative to the implementation's site-packages directory
+# (then it must start with a non-slash character).
+#
+# When unset, the modules will be installed in the site-packages root.
+#
+# Can be set indirectly through the python_moduleinto() function.
+#
+# Example:
+# @CODE
+# src_install() {
+#   local python_moduleroot=bar
+#   # installs ${PYTHON_SITEDIR}/bar/baz.py
+#   python_foreach_impl python_domodule baz.py
+# }
+# @CODE
+
+# @FUNCTION: python_moduleinto
+# @USAGE: <new-path>
+# @DESCRIPTION:
+# Set the current module root. The new value will be stored
+# in the 'python_moduleroot' environment variable. The new value need
+# be relative to the site-packages root.
+#
+# Alternatively, you can set the variable directly.

+# for all enabled implementations, and compiled afterwards.
