* tools/find-scanner.c: Explicitly state that find-scanner won't
 	  find non-SCSI scanners.
	* doc/scanimage.man: Add examples for SANE device names.
	* frontend/scanimage.c: Output message when no devices are found.
	  Add example for devicename to --help message. Print warning
	  when a Unix devicename is used instead of a SANE device. Removed
	  compiler warning.
	* TODO: Removed entries about the fgets and include issues in
 	  umax. Removed entries about scanimage device name
 	  documentation. Added a point about xscanimage problems with the
 	  new GIMP API.
	* backend/mustek.* doc/sane-mustek.man: Update to Mustek backend
 	  1.0-98. Fixed segmentation fault in sane_init. Enabled double
 	  buffering. Clear inquiry buffer before using. Paragon 1200 SP now
 	  uses LD_BLOCK color correction. Removed LD MFS (wasn't used
 	  anymore). Fix sane_cancel for Paragon series II scanners. Fix
 	  halftone and grain for Paragon series II scanners. Backtracking is
 	  used automaticly by all scanners now. Some safety checks, code
 	  cleanup and more debug output. Details are in
	  backend/mustek.CHANGES.
