+# - Functions to help assemble a standalone bundle application.
+# A collection of CMake utility functions useful for dealing with .app
+# bundles on the Mac and bundle-like directories on any OS.
+#
+# The following functions are provided by this module:
+# fixup_bundle
+# copy_and_fixup_bundle
+# verify_app
+# get_bundle_main_executable
+# get_dotapp_dir
+# get_bundle_and_executable
+# get_bundle_all_executables
+# get_item_key
+# clear_bundle_keys
+# set_bundle_key_values
+# get_bundle_keys
+# copy_resolved_item_into_bundle
+# copy_resolved_framework_into_bundle
+# fixup_bundle_item
+# verify_bundle_prerequisites
+# verify_bundle_symlinks
+# Requires CMake 2.6 or greater because it uses function, break and
+# PARENT_SCOPE. Also depends on GetPrerequisites.cmake.
+#
+# FIXUP_BUNDLE(<app> <libs> <dirs>)
+# Fix up a bundle in-place and make it standalone, such that it can be
+# drag-n-drop copied to another machine and run on that machine as long as all
+# of the system libraries are compatible.
+#
+# If you pass plugins to fixup_bundle as the libs parameter, you should install
+# them or copy them into the bundle before calling fixup_bundle. The "libs"
+# parameter is a list of libraries that must be fixed up, but that cannot be
+# determined by otool output analysis. (i.e., plugins)
+#
+# Gather all the keys for all the executables and libraries in a bundle, and
+# then, for each key, copy each prerequisite into the bundle. Then fix each one
+# up according to its own list of prerequisites.
+#
+# Then clear all the keys and call verify_app on the final bundle to ensure
+# that it is truly standalone.
+#
+# COPY_AND_FIXUP_BUNDLE(<src> <dst> <libs> <dirs>)
+# Makes a copy of the bundle <src> at location <dst> and then fixes up the
+# new copied bundle in-place at <dst>...
+#
+# VERIFY_APP(<app>)
+# Verifies that an application <app> appears valid based on running analysis
+# tools on it. Calls "message(FATAL_ERROR" if the application is not verified.
+#
+# GET_BUNDLE_MAIN_EXECUTABLE(<bundle> <result_var>)
+# The result will be the full path name of the bundle's main executable file
+# or an "error:" prefixed string if it could not be determined.
+#
+# GET_DOTAPP_DIR(<exe> <dotapp_dir_var>)
+# Returns the nearest parent dir whose name ends with ".app" given the full
+# path to an executable. If there is no such parent dir, then simply return
+# the dir containing the executable.
+#
+# The returned directory may or may not exist.
+#
+# GET_BUNDLE_AND_EXECUTABLE(<app> <bundle_var> <executable_var> <valid_var>)
+# Takes either a ".app" directory name or the name of an executable
+# nested inside a ".app" directory and returns the path to the ".app"
+# directory in <bundle_var> and the path to its main executable in
+# <executable_var>
+#
+# GET_BUNDLE_ALL_EXECUTABLES(<bundle> <exes_var>)
+# Scans the given bundle recursively for all executable files and accumulates
+# them into a variable.
+#
+# GET_ITEM_KEY(<item> <key_var>)
+# Given a file (item) name, generate a key that should be unique considering
+# the set of libraries that need copying or fixing up to make a bundle
+# standalone. This is essentially the file name including extension with "."
+# replaced by "_"
+#
+# This key is used as a prefix for CMake variables so that we can associate a
+# set of variables with a given item based on its key.
+#
+# CLEAR_BUNDLE_KEYS(<keys_var>)
+# Loop over the list of keys, clearing all the variables associated with each
+# key. After the loop, clear the list of keys itself.
+#
+# Caller of get_bundle_keys should call clear_bundle_keys when done with list
+# of keys.
+#
+# SET_BUNDLE_KEY_VALUES(<keys_var> <context> <item> <exepath> <dirs>
+# <copyflag>)
+# Add a key to the list (if necessary) for the given item. If added,
+# also set all the variables associated with that key.
+#
+# GET_BUNDLE_KEYS(<app> <libs> <dirs> <keys_var>)
+# Loop over all the executable and library files within the bundle (and given
+# as extra <libs>) and accumulate a list of keys representing them. Set
+# values associated with each key such that we can loop over all of them and
+# copy prerequisite libs into the bundle and then do appropriate
+# install_name_tool fixups.
+#
+# COPY_RESOLVED_ITEM_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)
+# Copy a resolved item into the bundle if necessary. Copy is not necessary if
+# the resolved_item is "the same as" the resolved_embedded_item.
+#
+# COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)
+# Copy a resolved framework into the bundle if necessary. Copy is not necessary
+# if the resolved_item is "the same as" the resolved_embedded_item.
+#
+# By default, BU_COPY_FULL_FRAMEWORK_CONTENTS is not set. If you want full
+# frameworks embedded in your bundles, set BU_COPY_FULL_FRAMEWORK_CONTENTS to
+# ON before calling fixup_bundle. By default,
+# COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE copies the framework dylib itself plus
+# the framework Resources directory.
+#
+# FIXUP_BUNDLE_ITEM(<resolved_embedded_item> <exepath> <dirs>)
+# Get the direct/non-system prerequisites of the resolved embedded item. For
+# each prerequisite, change the way it is referenced to the value of the
+# _EMBEDDED_ITEM keyed variable for that prerequisite. (Most likely changing to
+# an "@executable_path" style reference.)
+#
+# This function requires that the resolved_embedded_item be "inside" the bundle
+# already. In other words, if you pass plugins to fixup_bundle as the libs
+# parameter, you should install them or copy them into the bundle before
+# calling fixup_bundle. The "libs" parameter is a list of libraries that must
+# be fixed up, but that cannot be determined by otool output analysis. (i.e.,
+# plugins)
+#
+# Also, change the id of the item being fixed up to its own _EMBEDDED_ITEM
+# value.
+#
+# Accumulate changes in a local variable and make *one* call to
+# install_name_tool at the end of the function with all the changes at once.
+#
+# If the BU_CHMOD_BUNDLE_ITEMS variable is set then bundle items will be
+# marked writable before install_name_tool tries to change them.
+#
+# VERIFY_BUNDLE_PREREQUISITES(<bundle> <result_var> <info_var>)
+# Verifies that the sum of all prerequisites of all files inside the bundle
+# are contained within the bundle or are "system" libraries, presumed to exist
+# everywhere.
+#
+# VERIFY_BUNDLE_SYMLINKS(<bundle> <result_var> <info_var>)
+# Verifies that any symlinks found in the bundle point to other files that are
+# already also in the bundle... Anything that points to an external file causes
+# this function to fail the verification.
