#
# 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

    Used in .bb files to split up dynamically generated subpackages of a

                      parentheses () to mark the part of this expression
                      that should be used to derive the module name (to be
                      substituted where %s is used in other function
                      arguments as noted below)
    output_pattern -- pattern to use for the package names. Must include %s.
    description    -- description to set for each package. Must include %s.
    postinst       -- postinstall script to use for all packages (as a
                      string)
    recursive      -- True to perform a recursive search - default False

                        file_regex: as above
                        output_pattern: as above
                        modulename: the module name derived using file_regex
    extra_depends  -- extra runtime dependencies (RDEPENDS) to be set for
                      all packages. The default value of None causes a
                      dependency on the main package (${PN}) - if you do
                      not want this, pass '' for this parameter.
    aux_files_pattern -- extra item(s) to be added to FILES for each
                      package. Can be a single string item or a list of
                      strings for multiple items.  Must include %s.
    postrm         -- postrm script to use for all packages (as a string)
    allow_dirs     -- True allow directories to be matched - default False
    prepend        -- if True, prepend created packages to PACKAGES instead
                      of the default False which appends them
    match_path     -- match file_regex on the whole relative path to the
                      root rather than just the file name
    aux_files_pattern_verbatim -- extra item(s) to be added to FILES for
                      each package, using the actual derived module name
                      rather than converting it to something legal for a
                      package name. Can be a single string item or a list
                      of strings for multiple items. Must include %s.
    allow_links    -- True to allow symlinks to be matched - default False
