39:
40: $0 renders texxml files into dvi files by copying the tex file
41: resulting from from texxml2latex.pl and the referenced eps files
42: into a temporary directory and running LaTeX on the .tex file.

50: If thre is a second argument, it will be used as the path to the

53: If the optional argument --with-filenames is included then
54: the filename for each fragment is stuck into the finished file.
