* Bootstrap nimble
Here it is the script that I am using to generate the nimble sources.
```
rm ~/.cache/nim/nimble_d/ -rf
nim cc --genScript src/nimble.nim
sed -i 's#-I.*nimble/src##' ~/.cache/nim/nimble_d/compile_nimble.sh
cp ~/Sources/nim/Nim/lib/nimbase.h ~/.cache/nim/nimble_d/
mkdir ~/.cache/nim/nim-workspace/ -p
rm -rf ~/Sources/nim/nim-workspace/scripts/nimble-linux/
cp -r ~/.cache/nim/nimble_d/ ~/Sources/nim/nim-workspace/scripts/nimble-linux/
rm ~/.cache/nim/nimble_d/ -rf
nim cc --os:windows --genScript src/nimble.nim
sed -i 's#-I.*nimble/src##' ~/.cache/nim/nimble_d/compile_nimble.bat
cp ~/Sources/nim/Nim/lib/nimbase.h ~/.cache/nim/nimble_d/
mkdir ~/.cache/nim/nim-workspace/ -p
rm -rf ~/Sources/nim/nim-workspace/scripts/nimble-windows/
cp -r ~/.cache/nim/nimble_d/ ~/Sources/nim/nim-workspace/scripts/nimble-windows/
```
* Update scripts/rebuild-nimble
* Use the revision of nimble sources
* Choosenim to bootstrap nim for nimble usage
