## use generate_requres -> read dub.selections.json and --> create something like dub(xxxx)

## Dont try to mimic ~/.dub/packages , since dub fetch will modify package dub.json/dub.sdl here by adding version field and converting dub.sdl to dub.json

# dcd's dubhash is located in common/ folder, so when building, DUB_PACKAGING_DIR will be dcd-version/common (since it is a dcb:common package) so , the dir.dirName is dcd-version. Situation is not the same as d-scanner, dfmt , their dubhash is located under root folder, so -C -n %{_version}/%{name}-%{_version} is a must. (-C strip root under archive file, -n create with nested folder)
## use <version>/<packgename>-<version> for all dubhash versioing d pacakge.
