+Signs all the APK files in a target-files zipfile, producing a new
+target-files zip.
+
+Usage:  sign_target_files_apks [flags] input_target_files output_target_files
+
+  -s  (--signapk_jar)  <path>
+      Path of the signapks.jar file used to sign an individual APK
+      file.
+
+  -e  (--extra_apks)  <name,name,...=key>
+      Add extra APK name/key pairs as though they appeared in
+      apkcerts.zip.  Option may be repeated to give multiple extra
+      packages.
+
+  -k  (--key_mapping)  <src_key=dest_key>
+      Add a mapping from the key name as specified in apkcerts.txt (the
+      src_key) to the real key you wish to sign the package with
+      (dest_key).  Option may be repeated to give multiple key
+      mappings.
+
+  -d  (--default_key_mappings)  <dir>
+      Set up the following key mappings:
+
+        build/target/product/security/testkey   ==>  $dir/releasekey
+        build/target/product/security/media     ==>  $dir/media
+        build/target/product/security/shared    ==>  $dir/shared
+        build/target/product/security/platform  ==>  $dir/platform
+
+      -d and -k options are added to the set of mappings in the order
+      in which they appear on the command line.
