+# This file introduces a template for calling embed_as_string_view.py.
+#
+# embed_as_string_view behaves like C++23 #embed, converting an input file into
+# an AK::StringView literal rather than a C-string literal. The literal will
+# be placed into a global variable, optionally with a namespace wrapping it.
+#
+# Note that the file must not contain any tokens that need to be escaped
+# in C++, or the script will fail to produce a valid C++ translation unit.
+#
+# Parameters:
+#
+#   input (required) [string]
+#
+#   output (required) [string]
+#
+#   variable_name (required) [string]
+#
+#   namespace (optional) [string]
+#
+# Example use:
+#
+#   embed_as_string_view("embed_my_file") {
+#     input = "MyFile.txt"
+#     output = "$root_gen_dir/MyDirectory/MyFile.cpp"
+#     variable_name = "my_file_contents"
+#     namespace = "My::NS"
+#   }

+# This file introduces templates for generating JS bindings for Web Platform
+# Objects using IDL files.
+#
+# The public generate_idl_bindings template invokes the binding generator
+# for each IDL file in the input idl_list. It creates two source_set targets
+# for the input target_name, one ending in "_generated" and one ending in
+# "_sources". The "_generated" target is simply the code generator invocation,
+# while the "_sources" target is the actual generated C++ sources files.
+#
+#
+# Parameters:
+#   idl_list (required) [string]
+#     List of IDL files that are all the same type.
+#     Expected to be an absolute path.
+#
+#   type (required) string
+#       "global", "iterable", "namespace", or "standard"
+#
+# Example use:
+#
+#  standard_idl_files = get_path_info(
+#    [
+#      "//Library/Foo.idl",
+#      "//Bar.idl"
+#    ],
+#    "abspath")
+#
+#  generate_idl_bindings("standard_idl_bindings") {
+#    idl_list = standard_idl_files
