# Template to create an Apple bundle containing a binary file (e.g. .app or
# .framework bundle).
#
# Arguments
#
#   - bundle_extension
#
#       extension of the bundle (e.g. "app", "framework", ...); must not
#       include the dot preceding the extension
#
#   - bundle_type
#
#       four letter code corresponding to the bundle type ("FMWK", "AAPL",
#       ...); used to fill the "Bundle OS Type code" value in the generated
#       Info.plist for the bundle
#
#   - bundle_identitier
#
#       bundle identitifier
#
#   - product_type
#
#       type of the generated bundle (used for Xcode project)
#
#   - output_name (optional)
#
#       name of the bundle without the extension; the bundle binary (i.e.
#       the application or the library) must have the same name; defaults
#       to $target_name
#
#   - display_name (optional)
#
#       display name of the bundle (e.g. the name that is displayed to the
#       user); defaults to $output_name
#
#   - info_plist (optional)
#
#       path to additional Info.plist to merge into the final bundle Info.plist
