Recently we added the wasm binaries to the `rerun-if-changed` list. The problem with that is that they have a later mtime than the `invoked.timestamp` file and this file's mtime is used to determine if the `build.rs` script needs to be re-run. The solution to this is that we copy the mtime of this `invoked.timestamp` file and add it to the wasm binaries. Then cargo/rustc doesn't constantly wants to rerun the `build.rs` script.

License
- Substrate Primitives (
sp-*), Frame (frame-*) and the pallets (pallets-*), binaries (/bin) and all other utilities are licensed under Apache 2.0. - Substrate Client (
/client/*/sc-*) is licensed under GPL v3.0 with a classpath linking exception.
The reason for the split-licensing is to ensure that for the vast majority of teams using Substrate to create feature-chains, then all changes can be made entirely in Apache2-licensed code, allowing teams full freedom over what and how they release and giving licensing clarity to commercial teams.
In the interests of the community, we require any deeper improvements made to Substrate's core logic (e.g. Substrate's internal consensus, crypto or database code) to be contributed back so everyone can benefit.
