ras2tiff, sgi2tiff, sgisv, and ycbcr are completely removed from
the distribution. The libtiff tools rgb2ycbcr and thumbnail are
only built in the build tree for testing. Old files are put in
new 'archive' subdirectory of the source repository, but not in
distribution archives. These changes are made in order to lessen
the maintenance burden.
PNM formats so that we will be able to test more of the tools.
While adding these test images I notice that bmp2tiff and gif2tiff
only support ancient versions of their respective formats.
test programs and scripts.
* test/tiffinfo.sh: A trivial example test script.
* test/common.sh: Added small script for setting the environment
used by script-based tests.
