A Christmas present for code generator principle explorers and learners: full version 0.6.5 of the earliest expanse of code generators

A Christmas present for explorers and learners of code generator principles: full version 0.6.5
of the earliest expanse code generator The full version of the earliest expanse code generator 0.6.5.
This release has only one stack, simplejee stack, and only one example GenerateSample
but it is complete and the simplest. A treasure for explorers and learners of code generator principles.
I will answer the principle question, but I will not fix the bug of this version (in fact, it has already been fixed in subsequent versions).
According to the file information, this version was completed in 2014.8.3
