# Please see SVN for a list of changes to this script.
#
#
# Features:
# -it's very configurable
# -it logs all important actions
# -it operates on list of "translation projects" in svn (including web pages)
# -svn checkout or update as needed on every single project
# -verbose checking for fuzzy and untranslated strings or just statistics (numbers of translated, fuzzy and untranslated strings) if required
# -checking the syntax of po file from svn if required
# -checking the syntax of pot file from svn if required
# -copying the *.pot file, *.po file and web page files for editing in working directory if required
# -testing for differences of *.po file from working copy if required
# -testing for differences of *.pot file from working copy if required
# -searching for new *.pot files in svn


# TODO:
# implement --password ARG to simplify svn authentication if used
# simplify web copying part
# more tests if target folder exist
#
# How to svn co single file (file.pot):
# svn checkout $url_of_big_dir $target_dir --depth=empty
# svn up $target_dir/$file_you_want
# testing web pages checkout
# better documentation
