This is a reasonable question.  :-)

At one point, Adobe's enscript utility not only dealt with ASCII  
text, it could do some manipulations of existing PostScript docs, and  
the psnup utility would not only do 1->2 or 1->4 layouts, it could  
extract pages back (ie, 2->1 and so forth).  It also handled page  
size conversions, such as A3->A4.  However, I recall doing a lot of  
this PostScript manipulation on a NeXT which had native Display  
PostScript imaging, and it might be the case that Adobe's PostScript  
manipulation tools were more capable on that platform then they would  
be elsewhere.

Also note that what is in ports is the GNU reimplementation of  
Adobe's enscript, and it may or may not be as capable....
