Where can I find out what various hyperref options do?

Where can I find a description of `hyperref` options, deeper than the one of the manual? I do not understand the meaning of several options. For instance, what is "redefines LaTeX internals" (option `implicit`), or "use guessable names for links" (option `hypertexnames`)?

Regarding those "guessable names", have a look at: What does the hyperref option hypertexnames do? –  Stefan Kottwitz Dec 15 '11 at 13:24
Welcome to TeX.sx! A tip: You can use backticks ``` to mark your inline code as I did in my edit. –  Torbjørn T. Dec 15 '11 at 13:27
Thanks to both. About the `hypertexnames` option, that was just an example. I would like a freely available and full description of all the `hyperref` options. –  ASdeL Dec 15 '11 at 13:33
If you are interested in descriptions that are "deeper than the one of the manual" - and by "manual" I assume you are referring to the user-friendly `hyperref` documentation - then your next available option would be the detailed (and perhaps cryptic) `hyperref` manual. My choice of names here is completely opposite to that of the filenames on CTAN...
The `hyperref` manual is literally a PDF version of the `.dtx` sources and is therefore filled with code (almost 17,000 lines of it, or just under 400 pages) and sparse comments.
For example, section 28 Automated LaTeX hypertext cross-reference (p 152) contains a more detailed discussion on the option `hypertexnames`. However, this is probably one of the few detailed discussion on options. The only alternative in my opinion is to keep the `hyperref` package options summary close by and search the manual for the relevant code that describes it.
