Typeset the source code documentation for TeX, e-TeX or pdfTeX
Other (as stated in the work)
This project typesets the source code documentation for 3 TeX engines: Knuth's TeX, e-TeX or pdfTeX—by default it typesets the source code for e-TeX. All .tex source files were extracted from the original WEB source code after processing via a Web2C-based workflow. To typeset the documentation for a particular engine, just uncomment the relevant line in main.tex and comment out the others.
