+# Autocompletion config for YouCompleteMe in V8.
+#
+# USAGE:
+#
+#   1. Install YCM [https://github.com/Valloric/YouCompleteMe]
+#          (Googlers should check out [go/ycm])
+#
+#   2. Profit
+#
+#
+# Usage notes:
+#
+#   * You must use ninja & clang to build V8.
+#
+#   * You must have run gyp_v8 and built V8 recently.
+#
+#
+# Hacking notes:
+#
+#   * The purpose of this script is to construct an accurate enough command line
+#     for YCM to pass to clang so it can build and extract the symbols.
+#
+#   * Right now, we only pull the -I and -D flags. That seems to be sufficient
+#     for everything I've used it for.
+#
+#   * That whole ninja & clang thing? We could support other configs if someone
+#     were willing to write the correct commands and a parser.
+#
+#   * This has only been tested on gTrusty.
