% This is piTeX, a set of macros I (Paul Isambert) use to
% typeset documentations for my packages (that's why it is
% archived on CTAN).
%
% Perhaps in the future, when this achieves some kind of
% format-like completude, it'll be publicly announced. In the
% meanwhile, a documentation exists (pitex-doc.pdf, also readable
% in a text editor as pitex-doc.txt).
%
%
% You can of course use those macros, but you are on your
% own, and the files will probably be modified without announcement.
% The file is supposed to be \input on plain TeX with LuaTeX, at least v.0.6.
%
%
% The files needed are:
%
% texapi.tex (an independent package for programming)
% yax.tex (an independent package for key=value interface)
% gates.tex and gates.lua (an independant package for overall architecture)
% navigator.tex (an independant package for PDF features)
% lua.ptx and base.ptxlua (Lua side)
% files.ptx (file management)
% fonts.ptx, fonts.ptxlua and foundry-settings.lua
% (fonts, should be independant some day; actually
% fonts.ptxlua can be used independantly, but there is
% no doc)
% sections.ptx (sectionning commands)
% blocks.ptx (text blocks)
% references.ptx (labels and references)
% verbatim.ptx (typesetting verbatim)
% inserts.ptx (footnotes and figures, a mess)
% output.ptx (output routine)
%
% The file i-pitex.lua is needed only to typeset the documentation with the
% Interpreter package.

% Date: November 2011.
