[OS X TeX] I do like ps4pdf questions

[Roger Hart]

Dear Herb,

Thanks very much for your expert suggestions.  I guess the *only* 
reason to consider using this altered script, over a second pdflatex 
run, is if processing is time-consuming. For some of my files, about 
100 pp., a single run can take over a minute on my PowerBook G4 (400 
MHz), possibly because there are a lot of Chinese characters to 
process.

Again, thanks very much,

Roger
