% Macros which write labels, citations and index entries on auxiliary files. % % 1. Some code was moved around so that all the labels and indexing stuff % would be together. % 2. Modified \makelabel, \printref and \label to be more like the LaTeX % commands \newlabel, \ref and \label, respectively. The commands: % \@xp, \@firstoftwo, \@secondoftwo, \namedef, \@ifundefined % \protectedwrite are adapted pieces of LaTeX code (\@xp is actually % AmSLaTeX's abbreviation of \expandafter). % 3. The upshot of 2. is that now underscore is allowed in labels and % index-entries and that the \makelabel commands written to the % manual.lab files have arguments that are no longer put in lowercase. % The labels formed inside TeX from the \makelabel commands maps % underscores to | (needed to be a non-active character) and then % converts to lowercase. % 4. Since GapDoc uses < and > in some of its labels a temporary re-defintion % of <#1> was necessary, inside \@xplowr. % - GG 2001/06/11, 2001/09/02
