PSUtils is a collection of useful utilities for manipulating PostScript documents. Programs included are psnup (for placing out several logical pages on a single sheet of paper), psselect (for selecting pages from a document), pstops (for general imposition), psbook (for signature generation for booklet printing), and psresize (for adjusting page sizes).
The release notes for 3.12 are misleading, because they include features introduced in 3.10 (for which there was no release announcement on Freecode). Thanks for making the announcements again (I think Freecode is an excellent way to keep abreast of free software announcements); maybe if there's a similar situation in future you could mark changes from previous releases?
For anyone who thinks the 2.3.24 release notes bear a suspicious resemblance to the 2.3.23 notes, I'm sorry, I used the wrong ones. The real notes are even less exciting: "a few tiny bug fixes, some code cleanup".
