# This hook creates a new PKGDESTDIR with 32bit files for x86_64.
#
# Variables that can be used in templates:
# - lib32depends: if set, 32bit pkg will use this rather than "depends".
# - lib32disabled: if set, no 32bit pkg will be created.
# - lib32files: additional files to add to the 32bit pkg (abs paths, separated by blanks).
# - lib32symlinks: makes a symlink from lib32 to lib of the specified file (basename).
# - lib32mode:
# * if unset only files for libraries will be copied.
# * if set to "full" all files will be copied.
