%% langsci-affiliations collects, orders, and outputs author-affiliation pairs.
%% It makes use of data types from LaTeX3.
%% 
%% The package is aimed to be helpful to class authors, i.e. those who design
%% and maintain document templates in publishing houses, universities, etc. The
%% package is probably of only limited use to document authors/end users.
%% 
%% langsci-affiliations was developed at Language Science Press to help in the
%% production of scientific texts in linguistics.
