+# Packaging process
+#
+# Executive summary: This class iterates over the functions listed in PACKAGEFUNCS
+# Taking D and splitting it up into the packages listed in PACKAGES, placing the
+# resulting output in PKGDEST.
+#
+# There are the following default steps but PACKAGEFUNCS can be extended:
+#
+# a) package_get_auto_pr - get PRAUTO from remote PR service
+#
+# b) perform_packagecopy - Copy D into PKGD
+#
+# c) package_do_split_locales - Split out the locale files, updates FILES and PACKAGES
+#
+# d) split_and_strip_files - split the files into runtime and debug and strip them.
+#    Debug files include debug info split, and associated sources that end up in -dbg packages
+#
+# e) fixup_perms - Fix up permissions in the package before we split it.
+#
+# f) populate_packages - Split the files in PKGD into separate packages in PKGDEST/<pkgname>
+#    Also triggers the binary stripping code to put files in -dbg packages.
+#
+# g) package_do_filedeps - Collect perfile run-time dependency metadata
+#    The data is stores in FILER{PROVIDES,DEPENDS}_file_pkg variables with
+#    a list of affected files in FILER{PROVIDES,DEPENDS}FLIST_pkg
+#
+# h) package_do_shlibs - Look at the shared libraries generated and autotmatically add any
+#    depenedencies found. Also stores the package name so anyone else using this library
+#    knows which package to depend on.
+#
+# i) package_do_pkgconfig - Keep track of which packages need and provide which .pc files
+#
+# j) read_shlibdeps - Reads the stored shlibs information into the metadata
+#
+# k) package_depchains - Adds automatic dependencies to -dbg and -dev packages
+#
+# l) emit_pkgdata - saves the packaging data into PKGDATA_DIR for use in later
+#    packaging steps
