% Abstract: Computations in algebraic combinatorics often boils down to           
% sparse linear algebra over some exact field. Such computations are              
% usually done in high level computer algebra systems like MuPAD or               
% Maple, which are reasonnably efficient when the ground field requires           
% symbolic computations.  However, when the ground field is, say Q or             
% Z/pZ, the use of external specialized libraries becomes necessary. This         
% document, geared toward developpers of such libraries, present a brief          
% overview of my needs, which seems to be fairly typical in the                   
% community.
