+Check the signatures of all APKs in a target_files .zip file.  With
+-c, compare the signatures of each package to the ones in a separate
+target_files (usually a previously distributed build for the same
+device) and flag any changes.
+
+Usage:  check_target_file_signatures [flags] target_files
+
+  -c  (--compare_with)  <other_target_files>
+      Look for compatibility problems between the two sets of target
+      files (eg., packages whose keys have changed).
+
+  -l  (--local_cert_dirs)  <dir,dir,...>
+      Comma-separated list of top-level directories to scan for
+      .x509.pem files.  Defaults to "vendor,build".  Where cert files
+      can be found that match APK signatures, the filename will be
+      printed as the cert name, otherwise a hash of the cert plus its
+      subject string will be printed instead.
+
+  -t  (--text)
+      Dump the certificate information for both packages in comparison
+      mode (this output is normally suppressed).

-Given a target-files zipfile, produces an OTA package that installs
-that build.  An incremental OTA is produced if -i is given, otherwise
-a full OTA is produced.
-
-Usage:  ota_from_target_files [flags] input_target_files output_ota_package
-
-  --board_config  <file>
-      Deprecated.
-
-  -k (--package_key) <key> Key to use to sign the package (default is
-      the value of default_system_dev_certificate from the input
-      target-files's META/misc_info.txt, or
-      "build/target/product/security/testkey" if that value is not
-      specified).
-
-      For incremental OTAs, the default value is based on the source
-      target-file, not the target build.
-
-  -i  (--incremental_from)  <file>
-      Generate an incremental OTA using the given target-files zip as
-      the starting build.
-
-  -v  (--verify)
-      Remount and verify the checksums of the files written to the
-      system and vendor (if used) partitions.  Incremental builds only.
-
-  -o  (--oem_settings)  <file>
-      Use the file to specify the expected OEM-specific properties
-      on the OEM partition of the intended device.
-
-  -w  (--wipe_user_data)
-      Generate an OTA package that will wipe the user data partition
-      when installed.
-
-  -n  (--no_prereq)
-      Omit the timestamp prereq check normally included at the top of
-      the build scripts (used for developer OTA packages which
-      legitimately need to go back and forth).
-
-  -e  (--extra_script)  <file>
-      Insert the contents of file at the end of the update script.
-
-  -a  (--aslr_mode)  <on|off>
-      Specify whether to turn on ASLR for the package (on by default).
-
-  -2  (--two_step)
-      Generate a 'two-step' OTA package, where recovery is updated
-      first, so that any changes made to the system partition are done
-      using the new recovery (new kernel, etc.).
-
-  --block
-      Generate a block-based OTA if possible.  Will fall back to a
-      file-based OTA if the target_files is older and doesn't support
-      block-based OTAs.
-
-  -b  (--binary)  <file>
-      Use the given binary as the update-binary in the output package,
-      instead of the binary in the build's target_files.  Use for
-      development only.
-
-  -t  (--worker_threads) <int>
-      Specifies the number of worker-threads that will be used when
-      generating patches for incremental updates (defaults to 3).

+Given a target-files zipfile, produces an OTA package that installs
+that build.  An incremental OTA is produced if -i is given, otherwise
+a full OTA is produced.
+
+Usage:  ota_from_target_files [flags] input_target_files output_ota_package
+
+  --board_config  <file>
+      Deprecated.
+
+  -k (--package_key) <key> Key to use to sign the package (default is
+      the value of default_system_dev_certificate from the input
+      target-files's META/misc_info.txt, or
+      "build/target/product/security/testkey" if that value is not
+      specified).
+
+      For incremental OTAs, the default value is based on the source
+      target-file, not the target build.
+
+  -i  (--incremental_from)  <file>
+      Generate an incremental OTA using the given target-files zip as
+      the starting build.
+
+  --full_radio
+      When generating an incremental OTA, always include a full copy of
+      radio image. This option is only meaningful when -i is specified,
+      because a full radio is always included in a full OTA if applicable.
+
+  -v  (--verify)
+      Remount and verify the checksums of the files written to the
+      system and vendor (if used) partitions.  Incremental builds only.
+
+  -o  (--oem_settings)  <file>
+      Use the file to specify the expected OEM-specific properties
+      on the OEM partition of the intended device.
+
+  -w  (--wipe_user_data)
+      Generate an OTA package that will wipe the user data partition
+      when installed.
+
+  -n  (--no_prereq)
+      Omit the timestamp prereq check normally included at the top of
+      the build scripts (used for developer OTA packages which
+      legitimately need to go back and forth).
+
+  -e  (--extra_script)  <file>
+      Insert the contents of file at the end of the update script.
+
+  -a  (--aslr_mode)  <on|off>
+      Specify whether to turn on ASLR for the package (on by default).
+
+  -2  (--two_step)
+      Generate a 'two-step' OTA package, where recovery is updated
+      first, so that any changes made to the system partition are done
+      using the new recovery (new kernel, etc.).
+
+  --block
+      Generate a block-based OTA if possible.  Will fall back to a
+      file-based OTA if the target_files is older and doesn't support
+      block-based OTAs.
+
+  -b  (--binary)  <file>
+      Use the given binary as the update-binary in the output package,
+      instead of the binary in the build's target_files.  Use for
+      development only.
+
+  -t  (--worker_threads) <int>
+      Specifies the number of worker-threads that will be used when
+      generating patches for incremental updates (defaults to 3).

-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
-
-  -e  (--extra_apks)  <name,name,...=key>
-      Add extra APK name/key pairs as though they appeared in
-      apkcerts.txt (so mappings specified by -k and -d are applied).
-      Keys specified in -e override any value for that app contained
-      in the apkcerts.txt file.  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:
-
-        $devkey/devkey    ==>  $dir/releasekey
-        $devkey/testkey   ==>  $dir/releasekey
-        $devkey/media     ==>  $dir/media
-        $devkey/shared    ==>  $dir/shared
-        $devkey/platform  ==>  $dir/platform
-
-      where $devkey is the directory part of the value of
-      default_system_dev_certificate from the input target-files's
-      META/misc_info.txt.  (Defaulting to "build/target/product/security"
-      if the value is not present in misc_info.
-
-      -d and -k options are added to the set of mappings in the order
-      in which they appear on the command line.
-
-  -o  (--replace_ota_keys)
-      Replace the certificate (public key) used by OTA package
-      verification with the one specified in the input target_files
-      zip (in the META/otakeys.txt file).  Key remapping (-k and -d)
-      is performed on this key.
-
-  -t  (--tag_changes)  <+tag>,<-tag>,...
-      Comma-separated list of changes to make to the set of tags (in
-      the last component of the build fingerprint).  Prefix each with
-      '+' or '-' to indicate whether that tag should be added or
-      removed.  Changes are processed in the order they appear.
-      Default value is "-test-keys,-dev-keys,+release-keys".

+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
+
+  -e  (--extra_apks)  <name,name,...=key>
+      Add extra APK name/key pairs as though they appeared in
+      apkcerts.txt (so mappings specified by -k and -d are applied).
+      Keys specified in -e override any value for that app contained
+      in the apkcerts.txt file.  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:
+
+        $devkey/devkey    ==>  $dir/releasekey
+        $devkey/testkey   ==>  $dir/releasekey
+        $devkey/media     ==>  $dir/media
+        $devkey/shared    ==>  $dir/shared
+        $devkey/platform  ==>  $dir/platform
+
+      where $devkey is the directory part of the value of
+      default_system_dev_certificate from the input target-files's
+      META/misc_info.txt.  (Defaulting to "build/target/product/security"
+      if the value is not present in misc_info.
+
+      -d and -k options are added to the set of mappings in the order
+      in which they appear on the command line.
+
+  -o  (--replace_ota_keys)
+      Replace the certificate (public key) used by OTA package
+      verification with the one specified in the input target_files
+      zip (in the META/otakeys.txt file).  Key remapping (-k and -d)
+      is performed on this key.
+
+  -t  (--tag_changes)  <+tag>,<-tag>,...
+      Comma-separated list of changes to make to the set of tags (in
+      the last component of the build fingerprint).  Prefix each with
+      '+' or '-' to indicate whether that tag should be added or
+      removed.  Changes are processed in the order they appear.
+      Default value is "-test-keys,-dev-keys,+release-keys".
