+ 			PSNUP README Patch 1
+ 
+ 			Chris Lewis
+ 
+ This release is a combination of two things: a generalized n-up processor
+ for postscript files, plus a shell wrapper script and manual page.
+ Ned Batchelder wrote the postscript n-up handling and postscript
+ compressor program, and I wrote the shell wrapper script and manual page.
+ I include the original README from Ned Batchelder below.  Note, however,
+ that the psnup shell script performs the parameter substitution that Ned
+ refers to.  Therefore, you don't have to do anything to the nup.* stuff.
+ 
+ Patch 1 note: I'm more than a little embarrassed about the difficulties
+ in the shell script and manual page.  That's what comes of not testing
+ the final version.  In particular, the manual page did not make it clear
+ that the origin for "-s" is 0 not 1, and the default should be 0 not 1,
+ and that the -r & -R implementation was reversed.  Hence the fixes to
+ psnup.sh and psnup.1.  As well, there was a bug in psc.c in that the
+ return from getchar() was defined as a char, which can cause infinite
+ loops on some machines.
+ 
+ Other changes include this little note in the README (because some people
+ were editting nup.* directly, which they don't need to) and a removal
+ of the "%!" from nup.post.ps.
+ 
+ Psroff (CAT & ditroff -2- HPLJ/ditroff/Postscript) has been
+ modified to utilize the nup.epi and nup.pro files.  So, you'll want
+ to keep this if you intend to use psroff.  Psroff 3.0 will be released
+ soon.
+ 
+ And finally, like all n-up programs, it is possible for it to be fooled.
+ Nup does what it does by redefining a few operators, such as initgraphics.
+ Be aware that some applications (tpscript seems to be one of them) will
+ foul up nup's definitions, and the results will not be what you intended.
+ -------------------------------------------
  	Nup is designed to be used as a wrap around any PostScript file.
  Simply prepend nup.pre.ps, and append nup.post.ps, and it should work. There
  are three tokens in nup.pre.ps which need to be changed before sending it to
