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. Full documentation is available in the doc subdirectory. Windows users: you may prefer the epspdf-setup package, which installs a version of epspdftk which requires no additional software beyond MiKTeX or TeX Live.
