+# Gen-ZAM, a templator for the Zeek Abstract Machine
+
+Zeek uses the `gen-zam` tool during its build, to synthesize operations in ZAM,
+the Zeek Abstract Machine. The main reason for why you might want to use this
+repository on its own is cross-compilation, for which you'll need `gen-zam` on
+the build host, much like `bifcl` and `binpac`.
