patchSynctex - Communication Between Editor and Viewer for Literate Programs
This utility eases the debugging of literate documents
('noweb' files) by patching the synchronization information
(the '.synctex(.gz)' file) produced by 'pdflatex' with
concordance information produced by 'Sweave' or 'knitr' and
'Sweave' or 'knitr' ; this allows for bilateral communication
between a text editor (visualizing the 'noweb' source) and a
viewer (visualizing the resultant 'PDF'), thus bypassing the
intermediate 'TeX' file.
