Note ~~~~ This spanish style for babel provides the functionality intented for the Spanish language when babel 3.7 comes to light. Very likely, its implementation will change in babel 3.7 because there are part of code for it to work with 3.6; thus, it's should be considered neither part of babel 3.7 nor babel 3.6. To repeat: These files are not part of the babel package but extend its functionality. When you find a problem with them, please contact Javier Bezos , not Johannes Braams. Installation procedure ~~~~~~~~~~~~~~~~~~~~~~ To use spanish typeset spanish.ins. The files spanish.ldf and esbst.sty are generated, which you should move to the babel directory. romanidx.tex is also generated, which may be placed anywhere you like. Note: the old spanish must be moved to a place where latex cannot find it. For further details typeset spanish.dtx, which regrettably is in Spanish only.
