;   COMPRESSOR    - either zlib or lzma
;   TITLE         - title                         (eg. "Panda3D SDK 1.9.0")
;   INSTALLDIR    - default install location      (eg. "C:\Panda3D-1.9.0-x64")
;   OUTFILE       - where to put the output file  (eg. "..\nsis-output.exe")
;
;   BUILT         - location of panda install tree.
;   SOURCE        - location of the panda source-tree if available, OR location of panda install tree.
;   INCLUDE_PYVER - version of Python that Panda was built with (eg. "3.8", "3.7-32")
;   REGVIEW       - either 32 or 64, depending on the build architecture.
