Usage:
|
|
python clean_dvi.py infile.dvi outfile.dvi
|
|
|
|
clean_dvi modifies the input .dvi file so that
|
|
dvips and yap (a dvi viewer on Windows) can find
|
|
any embedded PostScript files whose names are protected
|
|
with "-quotes.
|
|
|
|
It works by:
|
|
1 translating the machine readable .dvi file to human
|
|
readable .dtl form,
|
|
2 manipulating any references to external files
|
|
3 translating the .dtl file back to .dvi format.
|
|
|
|
It requires dv2dt and dt2dv from the DTL dviware package
