[tex-live] /graphics/prerex

[Bob Tennent]

I'd like to get at least some of this into texlive. There are basically
four parts:

 + prerex.sty:  macros; should be unproblematic

 + prerex: an interactive editor, this is now (version 6.0) packaged as a 
   gzipped tarball with an autoconf-generated configure script; should be 
   straightforward.

 + vprerex: a graphical front-end and viewer for the editor; this uses Qt4
   and poppler libraries, and is configured using qmake;  this may not be
   suitable for texlive

 + patches for kpdf/okular; these were useful before the development of 
   vprerex but are now deprecated.

Thanks.
