      "tif" {
        eval exec {gdal_translate $path.ppm $path.tif -of GTIFF}
        eval exec "rm $path.ppm"
      }

This is a good example of how /not/ to use "exec" in Tcl. A command is
a list of strings, not a string. This issue plagues Bourne-shell
scripts do the lack of support for lists. Tcl has lists, so there's no
reason for this type of issue to arise.

The above should be:

  exec gdal_translate $path.ppm $path.tif -of GTIFF
  exec rm $path.ppm

I strongly suspect that the same issue applies to most (if not all) of
the other occurrences of "eval exec ..." in gis.m (a quick "grep"
finds 50 of them).
