+# If you don't need to do a full clean build but would like to touch
+# a file or delete some intermediate files, add a clean step to the end
+# of the list. These steps will only be run once, if they haven't been
+# run before.
+#
+# E.g.:
+# $(call add-clean-step, touch -c external/sqlite/sqlite3.h)
+# $(call add-clean-step, rm -rf $(PRODUCT_OUT)/obj/STATIC_LIBRARIES/libz_intermediates)
+#
+# Always use "touch -c" and "rm -f" or "rm -rf" to gracefully deal with
+# files that are missing or have been moved.
+#
+# Use $(PRODUCT_OUT) to get to the "out/target/product/blah/" directory.
+# Use $(OUT_DIR) to refer to the "out" directory.
+#
+# If you need to re-do something that's already mentioned, just copy
+# the command and add it to the bottom of the list. E.g., if a change
+# that you made last week required touching a file and a change you
+# made today requires touching the same file, just copy the old
+# touch step and add it to the end of the list.
+#
+# ************************************************
+# NEWER CLEAN STEPS MUST BE AT THE END OF THE LIST
+# ************************************************
+
+# For example:
+#$(call add-clean-step, rm -rf $(OUT_DIR)/target/common/obj/APPS/AndroidTests_intermediates)
+#$(call add-clean-step, rm -rf $(OUT_DIR)/target/common/obj/JAVA_LIBRARIES/core_intermediates)
+#$(call add-clean-step, find $(OUT_DIR) -type f -name "IGTalkSession*" -print0 | xargs -0 rm -f)
+#$(call add-clean-step, rm -rf $(PRODUCT_OUT)/data/*)

+/*
+ * Implementation of the POSIX open_memstream() function, which Linux has
+ * but BSD lacks.
+ *
+ * Summary:
+ * - Works like a file-backed FILE* opened with fopen(name, "w"), but the
+ * backing is a chunk of memory rather than a file.
+ * - The buffer expands as you write more data. Seeking past the end
+ * of the file and then writing to it zero-fills the gap.
+ * - The values at "*bufp" and "*sizep" should be considered read-only,
+ * and are only valid immediately after an fflush() or fclose().
+ * - A '\0' is maintained just past the end of the file. This is not included
+ * in "*sizep". (The behavior w.r.t. fseek() is not clearly defined.
+ * The spec says the null byte is written when a write() advances EOF,
+ * but it looks like glibc ensures the null byte is always found at EOF,
+ * even if you just seeked backwards. The example on the opengroup.org
+ * page suggests that this is the expected behavior. The null must be
+ * present after a no-op fflush(), which we can't see, so we have to save
+ * and restore it. Annoying, but allows file truncation.)
+ * - After fclose(), the caller must eventually free(*bufp).
+ *
+ * This is built out of funopen(), which BSD has but Linux lacks. There is
+ * no flush() operator, so we need to keep the user pointers up to date
+ * after each operation.
+ *
+ * I don't think Windows has any of the above, but we don't need to use
+ * them there, so we just supply a stub.

+# Optionally, after the tag names can be put a description for the value(s)

+ * WARNING WARNING WARNING WARNING
+ *
+ * This program runs as set-uid root on Android production devices.
+ * Be very conservative when modifying it to avoid any serious
+ * security issue. Keep in mind the following:
+ *
+ * - This program should only run for the 'root' or 'shell' users
+ *
+ * - Statically link against the C library, and avoid anything that
+ * is more complex than simple system calls until the uid/gid has
+ * been dropped to that of a normal user or you are sure to exit.
+ *
+ * This avoids depending on environment variables, system properties
+ * and other external factors that may affect the C library in
+ * unpredictable ways.
+ *
+ * - Do not trust user input and/or the filesystem whenever possible.
+ *
+ * Read README.TXT for more details.
+ *
+ *
+ *
+ * The purpose of this program is to run a command as a specific
+ * application user-id. Typical usage is:
+ *
+ * run-as <package-name> <command> <args>
+ *
+ * The 'run-as' binary is setuid, but will check the following:
+ *
+ * - that it is invoked from the 'shell' or 'root' user (abort otherwise)
+ * - that '<package-name>' is the name of an installed and debuggable package
+ * - that the package's data directory is well-formed (see package.c)
+ *
+ * If so, it will cd to the package's data directory, drop to the application's
+ * user id / group id then run the command there.
+ *
+ * This can be useful for a number of different things on production devices:
+ *
+ * - Allow application developers to look at their own applicative data
+ * during development.
+ *
+ * - Run the 'gdbserver' binary executable to allow native debugging
