+# @FUNCTION: perl_domodule
+# @USAGE: perl_domodule [options] <files>
+# @DESCRIPTION:
+# Installs files in paths where they can be found in the default
+# Perl runtime.
+#
+# Note: Should only be used in src_install or pkg_preinst
+# anywhere else will do the wrong thing or die.
+#
+# The contents of the <files> list are copied into Perls Vendor library path
+# as follows:
+# @CODE
+#   # install perl/File.pm as Samba::File
+#   pushd perl/
+#   perl_domodule -C Samba File.pm
+#
+#   # install perl/ recursively under VENDORLIB/Samba/
+#   pushd perl/
+#   perl_domodule -C Samba -r .
+# @CODE
+#
+# @CODE
+#   options:
+#       -C Target/Name
+#          The subdirectory relative to the Perl VENDOR_LIB
+#          to install into.
+#
+#          defaults to ""
+#       -r
+#          Install directories recursively ( see doins )
+#          files:
+#          list of .pm files to install to VENDORLIB
+# @CODE
