+# This script provides functions to list the .dll, .dylib or .so files that an
+# executable or shared library file depends on. (Its prerequisites.)
+#
+# It uses various tools to obtain the list of required shared library files:
+# dumpbin (Windows)
+# ldd (Linux/Unix)
+# otool (Mac OSX)
+#
+# The following functions are provided by this script:
+# gp_append_unique
+# is_file_executable
+# gp_item_default_embedded_path
+# (projects can override with gp_item_default_embedded_path_override)
+# gp_resolve_item
+# (projects can override with gp_resolve_item_override)
+# gp_resolved_file_type
+# gp_file_type
+# get_prerequisites
+# list_prerequisites
+# list_prerequisites_by_glob
+#
+# Requires CMake 2.6 or greater because it uses function, break, return and
+# PARENT_SCOPE.
