Once you have prepared a font family file with the name `f-<famname>.opm` and
\TeX/ can see it in your filesystem then you can type \^`\fontfam``[<famname>]` and
the file is read, so the information about the font family is loaded. The name
`<famname>` must be lowercase and without spaces in the file name
`f-<famname>.opm`. On the other hand, the `\fontfam` command is more tolerant:
you can write uppercase letters and spaces here. The spaces are ignored and
uppercase letters are converted to lowercase.
For example `\fontfam [LM Fonts]` is equivalent to `\fontfam [LMfonts]` and both
commands load the file `f-lmfonts.opm`.

You can use your font file in sense of the previous paragraph without
registering it. But problem is that such families are not listed when
`\fontfam[?]` is used and it is not included in the font catalog when
`\fontfam[catalog]` is printed. The list of families taken in the catalog and
listed on the terminal is declared in two files: `fams-ini.opm` and
`fams-local.opm`. The second file is optional. Users can create it and write to
it the information about user-defined families using the same syntax as in
existed file `fams-ini.opm`.

The information from the user's `fams-local.opm` file has precedence.
For example `fams-ini.opm` declares aliases Times$\to$Termes etc. If you
have the original Times purchased from Adobe then you can register your
declaration of Adobe's Times family in `fams-local.opm`. When a user writes
`\fontfam[Times]` then the original Times (not Termes) is used.

The `fams-ini.opm` and `fams-local.opm` files can use the macros
\~`\_faminfo`, \~`\_famalias` and \~`\_famtext`. See the example from
`fams-ini.tex`:

{\everytt={\typosize[8/10]\_let\_printverbline=\_printcodeline \medskip}
 \def\docfile{fams-ini.opm}
\verbinput (3-28) fams-ini.opm
... etc.
}
\medskip

The \^`\_faminfo` commad has the syntax:
\begtt \catcode`\<=13
\_faminfo [<Family Name>] {<comments>} {<file-name>}
     { <mod-plus-vars> }
\endtt
%
The `<mod-plus-vars>` data is used only when printing the catalog. It consists of
one or more pairs `<mods>: {<vars>}`.
For each pair: each modifier (separated by comma) is applied to each
variant selector in <vars>
and prepared samples are printed. The `-` character means no modifiers
should be applied.

The \^`\_famalias` declares an alias to the last
declared family.

The \^`\_famtext` writes a line to the terminal and the log file when all
families are listed.

The \^`\_famfrom` saves the information about font type foundry or
manufacturer or designer or license owner. You can use it before `\_faminfo`
to print `\_famfrom` info into the catalog.
The `\_famfrom` data is applied to each following declared families until new
`\_famfrom` is given. Use `\_famfrom {}` if the information is not known.
