Documentation for NimX is unclear.
I cannot seem to find a solution to changing some of the attributes of "Builder".

I'm trying to do it like this after looking through the code:
```nim
import nimx/naketools
import strformat

const
    appName           = "CollectiveGallery"
    appVersion        = "1.0"
    javaPackageId     = &"eu.example.{appName}"
    activityClassName = &"{javaPackageId}.MainActivity"
    mainFile          = "src/CollectiveGallery"
    bin               = mainFile


var cgBuild = newBuilder() # cg = CollectiveGallery

cgBuild.appName           = appName
cgBuild.appVersion        = appVersion
cgBuild.javaPackageId     = javaPackageId
cgBuild.activityClassName = activityClassName
cgBuild.mainFile          = mainFile

beforeBuild(cgBuild)
```

But, as expected, this doesn't work and I'm met with a `SIGSEGV` error.

There also doesn't seem to be a way to change what name the binary ends up as.
