The saned(8) man page should be used to describe the behavior of saned
itself. The information about configuring inetd, xinetd, or systemd to
launch saned - while it is helpful - belongs in a separate location.
Keep in mind that distribution packages usually configure the service
automatically, and they may ship with their own specific instructions.
(For example, update-inetd can be used in Debian and its derivatives.)
This change moves this information from the man page into a new file,
making it more concise as well. Working examples are moved to separate
files that can be copied directly from the source tree to the system.
This cuts out some duplicate code, and enables us to reuse this
logic for PNG, JPEG, and any other future output format.
sanei_load_icc_profile also allows us to know that an ICC profile
file is not long enough before we start to write it to the output;
this should prevent poorly-written software from overflowing into
image data when they read the bad profile based on its length.
This ought to get rid of the last empty compilation unit warnings. This
merges libfelib.la with liblib.la. The former was always used together
with the latter. The latter was only ever used without the former when
linking backends and tools.
Tools might want to use the getopt functions, backends might just want
to use MD5.
Several variables are considered "user variables" by the GNU Standards.
This means that the user can pass these to their ./configure and make
invocations as they see fit. These variables include CPPFLAGS, CFLAGS
and LDFLAGS.
This changeset pushes our use of these variables to the automake shadow
variables, AM_CPPFLAGS, AM_CFLAGS and AM_LDFLAGS, so that user variables
will no longer clobber flags required in order to build.
The AC_SUBST and PKG_CHECK_MODULE invocations in configure.ac as well as
acinclude.m4 are sufficient to trigger automake to insert initialization
logic for the variables these introduce. There is no need to do this by
hand. Wherever these values are needed, it is better to use a variable.
This allows for one-off overrides on the make command-line (without the
need to run ./configure) for one thing.
using backend debugging using SANE_DEBUG_xxx to be used for saned controlled
scanning when using socket activation. When only the socket is received we
use the existing code path.
