-% This file is a variation of the file pdfsync4context.tex that ships
-% with the pdfsync package (used by iTeXMac and TeXShop) by Piero
-% D'Ancona and Jérôme Laurens. I made the macros a bit more efficient
-% and added some basic tracing options as well as a few more options.
-% I made this one while playing a bit with the Mac and TeX). Maybe I'll
-% add a bit of support to the kernel in in order to get rid of redundant
-% markers. Also, this had better be rewritten in a bit less \pdf
-% dependent way so that it can also be supported by dvipdfmx. I could
-% write a generic file as well, but since there is already support for
-% other packages I'll not do that (now).
