attaching improved

        * Improved: Error checking for the output filename selection.
        * Added: Ask back if an existing file should really be overwritten.
        * Added a couple of TODO entries.
        * Completed TODO:
                20051031 replace deprecated gtk.Combo with gtkComboBox or BH's
                         Sketch.UI.gtkmisc.CommonComboBox or so.
          so there are no deprecation warning in anymore.

The new is improved.
Obviously I cannot fix 5., so this remains untouched.
4. was done easily.

As for 1.,2. and 3.:
I have decided to actually build a string
for a command that would use a pipe for printing.
The reason is that the argv usage of popen* is not really documented
and with the argv usage I cannot create a pipe directly.
Simple, but sufficient shell argument quoting is implemented now.

In addition I have improved the error checking.

I had a look at this.  Some relatively simple things that should be fixed:

1. It assembles shell commands as a string without doing proper quoting of e.g. filenames.  Best is to avoid assembling a command as a single string completely and to always use a list of argv components.  The popen functions in Python accept those too.  Best would be to use the subprocess module from Python 2.4 (that would require raising the minimum python version I think)

2. If not explicitly selecting a file to write to, the plugin writes to a file called "" in the current directory.  This might overwrite existing files and it may not work sometimes since the current working directory might mot be writable.  The plugin should use proper temporary files or pipe the output of poster directly to lpr, or somesuch.

3. the logic of deleting looks wrong:

        if outfile and == "":

This could delete a file the user wanted to create explicitly. Keep a separate flag of whether there's a file that needs to be removed.

4. at least one typo:  orrured instead of occurred.

5. This shouldn't be a PluginCompound plugin.  It doesn't define a new object type. The only reason this isn't a problem yet is that Skencil 0.7 doesn't have a menu for plugin types yet.
For to be loaded automatically, Skencil needs a new plugin type, though.

Obviously the "ΓΌ" in the TODO comment needs to go
before applying the patch.

Skencil Tool dialog for printing large ps poster via the "poster" tool. Originally by Markus Rechtien.
Tested with Skencil CVS from 20051029.

This is usable, but also
see the TODO list at the top of the file.

I suggest placing the file in a freshly created directory
call "Tools" below "Plugins".
So you get Plugins/Tools/
