* aclocal.m4 configure: Fixed some bugs concerning link checks for libsane.
* src/xscanimage.c: Use g_free for memory acquired by g_new.
* TODO: Removed entries about g_free and ac_local.m4.
* TODO: Removed entry about stiff.*
* src/xscanimage.c: Removed support for SANE_DEFAULT_DEVICE. Using
only this device without giving the user the ability to change to
other devices isn't the intended behaviour.
* TODO: Entries about SANE_DEFAULT_DEVICE and DBG output.
* src/xscanimage.c: Added suport for DBG messages. Added only a
few messages including a more verbose output when xscanimage
can't find any devices. Added support for SANE_DEFAULT_DEVICE.
* doc/xscanimage.man: Documented support for SANE_DEFAULT_DEVICE and
SANE_DEBUG_XSCANIMAGE.
* README: Added information for developers and link to SANE website.
* TODO: Updated.
* INSTALL: Added link to GIMP website.
* src/xcam.c: Application is exited when window is closed (by
window manager)
