saners

in particular genesys_gl847

a query or two about <backend>.conf file

  1) do all, most, some backends support such runtime argument
     alterations?

  2) i see scanimage is checking for and reading ./genesys.conf
     and /opt/csw/etc/sane.d/genesys.conf

  3) i've tried to enter options in ./genesys.conf, but have
     not been able to get them to a) work or b) cause an
     error or warning.  is there anyplace in the sane documentation
     world that defines/describes the format for these arguments
     placed in a <backend.conf> file?

     i seem to think i've seen something like that but i'm not
     able to re-find it!  rtfm'ed sane.7, scanimage, sane-genesys
     sane-test and grep'ed around looking for '\.conf'

     ah-ha! sane-u12 -- but those lines don't work either

     tried lots of variations including
           option='flag:arg'
           option flag arg
           option -flag=arg
           option="-flag arg"


if anyone provides guidance even if pointer(s) to relevant code
i will take/make time to write-up a manpageish file and submit
for incorporation ...

thanks
