+  exec_script(filename,

+              input_conversion = "",
+              file_dependencies = [])
+
+  Runs the given script, returning the stdout of the script. The build
+  generation will fail if the script does not exist or returns a nonzero exit
+  code.
+
+  The current directory when executing the script will be the root build
+  directory. If you are passing file names, you will want to use the
+  rebase_path() function to make file names relative to this path (see "gn help
+  rebase_path").
+
+Arguments:
+
+  filename:
+      File name of python script to execute. Non-absolute names will be treated
+      as relative to the current build file.
+
+  arguments:
+      A list of strings to be passed to the script as arguments. May be
+      unspecified or the empty list which means no arguments.
+
+  input_conversion:
+      Controls how the file is read and parsed. See "gn help input_conversion".
+
+      If unspecified, defaults to the empty string which causes the script
+      result to be discarded. exec script will return None.
+
+  dependencies:
+      (Optional) A list of files that this script reads or otherwise depends
+      on. These dependencies will be added to the build result such that if any
+      of them change, the build will be regenerated and the script will be
+      re-run.
+
+      The script itself will be an implicit dependency so you do not need to
+      list it.
+
+Example
+
+  all_lines = exec_script(
+      "myscript.py", [some_input], "list lines",
+      [ rebase_path("data_file.txt", root_build_dir) ])

+  # This example just calls the script with no arguments and discards the
+  # result.
