+
+# Compile a flatbuffer.
+#
+# sources
+# Specifies the sources to compile.
+#
+# flatc_out_dir (optional)
+# Specifies the path suffix that output files are generated under. This
+# path will be appended to root_gen_dir.
+#
+# Targets that depend on the proto target will be able to include the
+# resulting flatbuffers header with an include like:
+# #include "dir/for/my_flatbuffer/buffer_generated.h"
+# If undefined, this defaults to matching the input directory for each
+# .fbs file (you should almost always use the default mode).
+#
+# deps (optional)
+# Additional dependencies.
+#
+# Parameters for compiling the generated code:
+#
+# defines (optional)
+# Defines to supply to the source set that compiles the generated source
+# code.
+#
+# extra_configs (optional)
+# A list of config labels that will be appended to the configs applying
+# to the source set.
+#
+# testonly (optional)
+# Boolean to indicate whether the generated source sets should be labeled
+# as testonly.
+#
+# Example:
+# flatbuffer("mylib") {
+# sources = [
+# "foo.fbs",
+# ]
