+message='usage: banchan <module> ... [<product>|arm|x86|arm64|x86_64] [eng|userdebug|user]
+
+banchan selects individual APEX modules to be built by the Android build system.
+Like "tapas", "banchan" does not request the building of images for a device but
+instead configures it for an unbundled build of the given modules, suitable for
+installing on any api-compatible device.
+
+The difference from "tapas" is that "banchan" sets the appropriate products etc
+for building APEX modules rather than apps (APKs).
+
+The module names should match apex{} modules in Android.bp files, typically
+starting with "com.android.".
+
+The product argument should be a product name ending in "_<arch>", where <arch>
+is one of arm, x86, arm64, x86_64. It can also be just an arch, in which case
+the standard product for building modules with that architecture is used, i.e.
+module_<arch>.
+
+The usage of the other arguments matches that of the rest of the platform
+build system and can be found by running `m help`'
