Here is how the various env files relate to each other:

• jvm
  • jvm-ce: + GraalVM Community Compiler
    • jvm-ce-libgraal: + libgraal
    • native-ce: + libpythonvm + Truffle Macro
  • jvm-ee: + Oracle GraalVM Compiler + Truffle enterprise + license + LLVM Runtime Native Enterprise
    • jvm-ee-libgraal: + libgraal
    • native-ee: + libpythonvm + Truffle Macro Enterprise + Native Image G1
      • native-ee-aux: + AuxiliaryEngineCache, - Native Image G1 (currently incompatible)

They all build the GraalPy standalone and nothing else to optimize build time.
