+# Perl package infrastructure
+#
+# This file implements an infrastructure that eases development of
+# package .mk files for Perl packages.
+#
+# See the Buildroot documentation for details on the usage of this
+# infrastructure
+#
+# In terms of implementation, this perl infrastructure requires
+# the .mk file to only specify metadata information about the
+# package: name, version, download URL, etc.
+#
+# We still allow the package .mk file to override what the different
+# steps are doing, if needed. For example, if <PKG>_BUILD_CMDS is
+# already defined, it is used as the list of commands to perform to
+# build the package, instead of the default perl behaviour. The
+# package can also define some post operation hooks.

+# inner-perl-package -- defines how the configuration, compilation and
+# installation of a perl package should be done, implements a
+# few hooks to tune the build process for perl specifities and
+# calls the generic package infrastructure to generate the necessary
+# make targets
+#
+#  argument 1 is the lowercase package name
+#  argument 2 is the uppercase package name, including an HOST_ prefix
+#             for host packages
+#  argument 3 is the uppercase package name, without the HOST_ prefix
+#             for host packages
+#  argument 4 is the type (target or host)
