Matrix reference link in the File Format document

[N. W. Perry]

Code:

There are many on-line references about transformation matrices, one such reference
is <a href="http://enphilistor.50megs.com/matrix.htm">The POV-RAY Matrix Page</a>

This link in File Format 1.0.2 is broken. Anyone have a suitable replacement?

By the far the most helpful resource I have found (albeit in Google-translated French) is:

together with the relevant sections of:
