@ bravais_TYP *brav_from_datei(char *symb,int almost,int zclass)
@ 
@ Reads a single bravais group from the catalog.
@ The symbol, the number almost and zclass are exactly as in the
@ standalone Datei resp. Bravais_catalog

@ symbol_out *get_symbol (file_name)
@ char *file_name;
@
@    This is a function for the 'Datei' programm.
@    It reads a group (bravais_TYP) from 'file_name' 
@    and additionally the name of another file stated in the
@    file 'file_name' beyond the group

@ void get_zentr(B)
@ symbol_out *B;
@
@    Another function for the 'Datei' programm.
@    It reads matrices form the file 'B->fn' and 
@    stores them in 'B->zentr'.
@    Reads additionally a filename stated beyond the matrices
@    and stores it in B->fn.
