% Should the following be loaded by default?

%D In order to be able to get journals expanded (or normalized or abbreviated) you need
%D to load a list:
%D
%D \starttyping
%D \btxloadjournallist[journals.txt] % the jabref list
%D \stoptyping

%D Sometimes we have verbose injections in an entry and these can be language
%D dependent, so we use labels.
%D
%D Because we want to mix rendering (in the manual) we need a namespace in label
%D texts:

%D Instead of texdefinitions without arguments, we could have used setups but in my
%D editor (hh, scite) the commands stand out better. It also saves an additional
%D component in the name (e.g. common:) because commands and setups have a different
%D namespace, so similar calls don't clash. Performance of definitions is somewhat
%D better.

%D \btxdoif... and \btxflush rely on the definitions in publ-imp-aps.lua:
%D fields that are not listed as required nor optional are IGNORED.

% First some helpers:

\starttexdefinition btx:aps:inject #link #content
    \ifconditional\btxinteractive
        \ifx\currentbtxinternal\empty
            #content
        \else
            \goto {
                #content
            } [
                #link
            ]
        \fi
    \else
        #content
    \fi
