This package (once part of the exsheets package), provides a
framework for providing multilingual features to a LaTeX
package. The package has its own basic dictionaries for
English, Brazilian, Catalan, Dutch, French, German and Spanish;
it aims to use translation material for English, Dutch, French,
German, Italian, Spanish, Catalan, Turkish, Croatian,
Hungarian, Danish and Portuguese from babel or polyglossia if
either is in use in the document. (Additional languages from
the multilingual packages may be possible: ask the author.)
