Purpose: gather together tips on writing portable [Tcl] and [Tk]
programs that will more likely run on many platforms.

   * See these PostScript files for observations on portable Tcl coding.

ftp://tcl.activestate.com/pub/tcl/doc/portable-tk.ps  and
ftp://tcl.activestate.com/pub/tcl/doc/portable-tk-slides.ps

   * Stay away from platform specific extensions, including [DDE], [Registry],
and [AppleScript].

   * See [Microsoft Windows] for some information about windows.

   * Use [file] rather than exec or self parsing file names, etc.
   * Avoid [exec] .
   * Avoid depending on [console], which currently is not available on [Unix].
   * Avoid [puts] to stdin and stdout, which might not be available on [Microsoft Windows].
