    Where available, use c++11 features to identify
    potential nullptr usage errors.

    python run-clang-tidy.py -clang-tidy-binary ~/software/clang+llvm-3.8.0-x86_64-linux-gnu-ubuntu-14.04/bin/clang-tidy -checks=-*,modernize-use-nullptr -header-filter=/home/grizonnetm/projets/otb/src/OTB/Modules/.*/.*/include/.* -j8 -fix -p ~/projets/otb/bin/release/OTB-clang3.8/ ~/projets/otb/src/OTB/Modules/*/*/src/*.cxx ~/projets/otb/src/OTB/Modules/*/*/app/*.cxx ~/projets/otb/src/OTB/Examples/*/*.cxx ~/projets/otb/src/OTB/Modules/*/*/test/*.cxx > ~/temporary/run-clang-tidy-nullptr-log.txt

    find . -type f -print -name "*.h" -o -name "*.txx" -o -name "*.cxx" |xargs perl -pi -e 's/nullptr/ITK_NULLPTR/g'

Used the following command:

find . \( -iname *.txx -and ! -path *ThirdParty* \) -exec perl -pi -w -e 's/__otb(.*)_txx/otb$1_txx/g;' {} \;
find . \( -iname *.h -and ! -path *ThirdParty* \) -exec perl -pi -w -e 's/__otb(.*)_h/otb$1_h/g;' {} \;

Fixes many, but not all, clang -Wreserved-id-macro warnings.

    clang-tidy tool can insert missing override keyword as a macro so that missing [optional] virtual identifiers can be easily added.

    build otb with clang 3.8 and use cmake option CMAKE_EXPORT_COMPILE_COMMANDS=ON. Most modules and third parties have been activated.

    cd src/Modules ; grep -nR "override" * > ~/temporary/override_otb.txt

This is a big one without much harm. It fixes incorrect spelling
and grammer when packaging OTB 5.0.0 and 5.2.0 for Debian.
Most of these changes are done by developers at DebianGIS.
For more info, I include the original patch header below.
Description: Fix some spelling errors to silence lintian
enabling  to concentrate on the real problem.
