1.5.3 Options for converting to PostScript
------------------------------------------
-For conversion the other way you may opt not to use pdftops even if it
-is available. In this case, the conversion will be done by Ghostscript.
-With older Ghostscript versions, characters may be converted to drawn
-shapes or little bitmaps, so use pdftops if available. With newer
-Ghostscript versions, with an eps2write rather than an epswrite output
-device, Ghostscript does a much better job.

-Under an older MikTeX without bundled pdftops, this is also the place to
-point the program to the location of pdftops.exe.
+For conversion to plain or Encapsulated PostScript, pdftops sometimes
+does a better job of preserving fonts than Ghostscript. Under Windows,
+current versions of both MiKTeX and TeX Live include pdftops. Still,
+you may opt not to use pdftops even if it is available, in which case

+Appendix A Requirements
+***********************
+
+Epspdftk consists of a GUI front end and a command-line back end.
+
+The command-line component, which can be used separately from the front
+end, requires ghostscript and a not too old TeX installation with
+luatex. It may further benefit from the presence of pdftops. MiKTeX
+and TeX Live for Windows meet these requirements out of the box.
+
+The front end requires a Tcl/Tk installation, or at least a tclkit
+runtime. TeX Live for Windows contains such a tclkit since late 2018,
+and epspdftk as a TeX Live package will make use of it. The minimum
+version is 8.5.
+
+For Windows there is an alternate epspdf-setup package on CTAN with an
+embedded Tcl/Tk runtime and a regular Windows installer, which also
+creates a menu shortcut and an uninstaller.
