+# Generate Android.bp for AOSP blob self-extractors.

+# For example, a blob package may contain:
+#   ./vendor
+#   └── qcom
+#       └── coral
+#           └── proprietary
+#               ├── lib64
+#               |   ├── libfoo.so
+#               |   └── libbar.so
+#               ├── libfoo.so
+#               └── libbar.so
+#
+# Generate prebuilt modules for these blobs:
+# $ export SYSTEM_EXT_SPECIFIC=true # If installing prebuilts to system_ext/ partition
+# $ ./generate-android-bp-for-blobs.sh ./vendor/qcom/coral/proprietary > Android.bp.txt
+# $ mv Android.bp.txt ${ANDROID_BUILD_TOP}/device/google/coral/self-extractors/qcom/staging/
+#
+# You may need to review the contents of Android.bp.txt as some of the blobs may
+# have unsatisfied dependencies. Add `check_elf_files: false` to bypass this
+# kind of build errors.
