Various parts of the Elisp manual refer to font families, but this
concept is nowhere explained (defined).
Using `i' in Info shows, for example, when checking for both `font'
and `family', these index entries:
`face-font-family-alternatives' `font-family-list' `x-family-fonts'
Look at the indexed doc and you will see that it talks about font
families, without ever saying what a font family is. This makes the
doc incomprehensible. Try to understand the `x-family-fonts'
description, for instance, without knowing what a font family is
(which is my case, FWIW).
Substitute `zophlog' for `family', then see if you understand:
Function: x-zophlog-fonts &optional zophlog frame
This function returns a list describing the available fonts for
zophlog ZOPHLOG on FRAME. If ZOPHLOG is omitted or `nil', this list
applies to all zophlogs, and therefore, it contains all available
fonts. Otherwise, ZOPHLOG must be a string; it may contain the
wildcards `?' and `*'.
The list describes the display that FRAME is on; if FRAME is
omitted or `nil', it applies to the selected frame's display
(*note Input Focus::).
Each element in the list is a vector of the following form:
[ZOPHLOG WIDTH POINT-SIZE WEIGHT SLANT
FIXED-P FULL REGISTRY-AND-ENCODING]
The first five elements correspond to face attributes; if you
specify these attributes for a face, it will use this font.
The last three elements give additional information about the font.
FIXED-P is non-`nil' if the font is fixed-pitch. FULL is the full
name of the font, and REGISTRY-AND-ENCODING is a string giving the
registry and encoding of the font.
That's as much as I understand - essentially nothing. Please define
and explain the notion `font family'.
Elisp manual nodes that use the unexplained notion `font family':
Faces
Face Attributes
Font Selection
Font Lookup
Fontsets

I don't think it's the place of the Emacs manual to define every single
operating system concept, especially one as self-explanatory as "font
family". But if it makes you happy, I can add it to the glossary.

I can't seem to find it in the glossary. On the other hand, I think
this is something that doesn't really belong in the manual.

I added a couple of xrefs to the Fonts node in the Emacs manual, from
which the meaning of "font families" should be obvious. Closing the
bug.
