# Build kzip files (source files for the indexing pipeline) for the given configuration,
# merge them and place the resulting all.kzip into $DIST_DIR.
# It is assumed that the current directory is the top of the source tree.
# The following enviromnet variables affect the result:
# TARGET_PRODUCT target device name, e.g., `aosp_blueline`
# TARGET_BUILD_VARIANT variant, e.g., `userdebug`
# OUT_DIR where the build is happening (./out if not specified)
# DIST_DIR where the resulting all.kzip will be placed
# XREF_CORPUS source code repository URI, e.g.,
# `android.googlesource.com/platform/superproject`
# The extraction might fail for some source files, so run with -k
