 % This bibliography style file is intended for texts in
 %   SPANISH
 % This is a labelled citation style similar to the standard alpha.bst,
 %   where labels are of the form Dal90 or DBK89.
 % It requires no extra package to interface to the main text.
 % The form of the \bibitem entries is
 %   \bibitem[label]{key}...
 % Usage of \cite is as follows:
 %   \cite{key} ==>>          [label]
 %   \cite[chap. 2]{key} ==>> [label, chap. 2]
 % The order in the reference list is by label.
