i found that the package 'libsane' is where all the backends are
contained.  but, several things depend on it, like hplip and hpjis,
which appears something i need for my HP printer to function.  ok i'll
remove it all for now in order to troubleshoot this....

the failure was due to permission denied, so i'll re-run as root.  how
to avoid running as root, though?

when i run 'sudo scanimage > test.pnm' the scanner does appear to
operate, the light starts moving down the glass, etc.  when it gets to
the end of the glass it doesn't stop, though.  is my x_range and y_range
too large?

so i press ^C to abort and it returns home.  the test.pnm, when opened
with eog (eye of gnome) appears all black but with some colorful
stripes/specs; there's no sign of the image i had on the glass.

i would like to share this test.pnm, where is a suitable place to put it?

secondly, how can i save all of the debug output of 'scanimage
>test.pnm' for you all to see?

thanks
