Epspdftk.tcl is a GUI ps/eps/pdf converter. Epspdf.tlu, its command-line backend, can be used by itself. Both are scripts: epspdf.tlu is written in texlua and uses the texlua script interpreter from TeX Live or MiKTeX. Epspdftk.tcl requires Tcl/Tk, either a full installation or a tclkit runtime. TeX Live already includes a minimal Tcl/Tk for Windows. Epspdftk.tcl can find the other files as long are they are all in the same directory. epspdf4tk.cmd is needed only when running epspdftk.tcl under Windows. Full documentation is available in the doc subdirectory. Windows MiKTeX users: the epspdftk GUI currently does not work with a MiKTeX installation. Therefore, the former epspdf-setup package is not being offered any more.
