[Kdenlive-devel] kdenlive.pot upgrade

[Jean-Michel POURE]

Dear all,

Could anyone be so kind to explain me how to extract a fresh kdenlive.pot file 
from source. make messages ? make update-pot?

In kdenlive/Makefile.am, there seems to be the following rule:

messages: rc.cpp
        LIST=`find . -name \*.h -o -name \*.hh -o -name \*.H -o -name \*.hxx 
-o -name \*.hpp -o -name \*.cpp -o -name \*.cc-o -name \*.cxx -o -name 
\*.ecpp -o -name \*.C`; \
        if test -n "$$LIST"; then \
         $(XGETTEXT) $$LIST -o $(podir)/kdenlive.pot; \
        fi

I am new to KDE development and do not understand the meaning of thei rc.cpp 
line. How can I upgrade kdenlive.pot file?

Kind regards,
Jean-Michel Pouré
