+
+  process_file_template(source_list, template)
+
+  process_file_template applies a template list to a source file list,
+  returning the result of applying each template to each source. This is
+  typically used for computing output file names from input files.
+
+  In most cases, get_target_outputs() will give the same result with shorter,
+  more maintainable code. This function should only be used when that function
+  can't be used (like there's no target or the target is defined in another
+  build file).
+
+Arguments
+
+  The source_list is a list of file names.
+
+  The template can be a string or a list. If it is a list, multiple output
+  strings are generated for each input.
+
+  The template should contain source expansions to which each name in the
+  source list is applied. See "gn help source_expansion".
+
+Example
+
+  sources = [
+    "foo.idl",
+    "bar.idl",
+  ]
+  myoutputs = process_file_template(
+      sources,
+      [ "$target_gen_dir/{{source_name_part}}.cc",
+        "$target_gen_dir/{{source_name_part}}.h" ])
+
+ The result in this case will be:
+    [ "//out/Debug/foo.cc"
+      "//out/Debug/foo.h"
+      "//out/Debug/bar.cc"
+      "//out/Debug/bar.h" ]
