This is a pure Lua library for low-level generation of PDF files.

This is code I wrote, oh gosh, about 10 years ago now, and I have no plans to develop it further. It is probably more valuable as a demonstration that it's really not that difficult to create a PDF file, than as a serious piece of equipment. However, I just tried the test script with Lua 5.1.5, using Firefox 33.0 as the PDF viewer, and it still works.
