Exiv2

I believe this has been done. I added a new tree <exiv2dir>/include/exiv2 to hold the public header files. The *int.hpp remain in src directory and are never published. Thomas and I worked on the header files while I was in Tenerife on vacation at New Year #1012

Here is my review of the samples. Only the following reference non public files:

614 rmills@rmillsmbp:~/gnu/exiv2/trunk/samples $ grep include *.cpp | grep '"'
metacopy.cpp:#include "utils.hpp" 
metacopy.cpp:#include "metacopy.hpp" 
path-test.cpp:#include "utils.hpp" 
tiffaddpath-test.cpp:#include "tiffcomposite_int.hpp" 
tiffaddpath-test.cpp:#include "makernote2_int.hpp" 
tiffaddpath-test.cpp:#include "tiffimage_int.hpp"

At some time, I we could create a distinct directory for testprogs such as path-test.cpp and the like. And perhaps metacopy.cpp should become metacopy-test.cpp as I believe the same capability is provided by exiv2 -e. The following are candidates for testprogs:

623 rmills@rmillsmbp:~/gnu/exiv2/trunk/samples $ ls *.cpp | grep -e test -e metacopy | sort
conntest.cpp
convert-test.cpp
easyaccess-test.cpp
exifdata-test.cpp
httptest.cpp
iotest.cpp
iptctest.cpp
key-test.cpp
largeiptc-test.cpp
metacopy.cpp
mmap-test.cpp
path-test.cpp
prevtest.cpp
remotetest.cpp
stringto-test.cpp
tiff-test.cpp
tiffaddpath-test.cpp
werror-test.cpp
write-test.cpp
write2-test.cpp
xmpparser-test.cpp

The samples would be reduced to:

$ ls *.cpp | grep -v -e test -v -e metacopy | sort
addmoddel.cpp
exifcomment.cpp
exifdata.cpp
exifprint.cpp
exifvalue.cpp
exiv2json.cpp
geotag.cpp
iptceasy.cpp
iptcprint.cpp
taglist.cpp
xmpparse.cpp
xmpsample.cpp
