[OS X TeX] ps2eps and bbox

[Michael Sharpe]

The PERL script ps2eps, which is supposed to construct a correct  
bounding box for a ps file, is useful but a bit buggy, as Herb Shulz  
pointed out in a commentary on one of his scripts. It depends  
crucially on a C program named bbox, which seems to makes errors of up  
to a couple of points in computing the bounding box. I've corrected  
some of those bugs, and it seems to improve the accuracy considerably,  
so that the 'tight' setting is now useful. I've emailed the author,  
Roland Bless, but have not yet heard back from him. Meanwhile, if  
anyone else is interested, I've detailed the corrections and posted  
the new Intel binary at

As bbox was installed as part of Mactex 2008, you will have to either  
replace /usr/texbin/bbox with the new version. or place the new  
version in a folder searched ahead of /usr/texbin in your PATH.

Note that this is primarily of interest to those working with eps  
files rather than directly with pdf graphics, but in my experience  
most publishers still want eps files, and that is the only form  
understood by PSTricks.
