# This target merges all po files with the current pot file,

# header with the PROJECT only, removing the VERSION part.
# This is done to keep the diff between releases small.
#
# NOTE:
# Removing obsolete msgids is not the recommended way to go.
# However, we've decided that in the specific case of iso-codes
# the benefit outweights the loss of information. Having only msgids
# with one (sometimes two or three) words, the fuzzy matching performed
# with obsolete msgids will not ease the translator's work, but
# will lead to confusing entries.
#
# However, if there is only a small change, we include the fuzzy
# entry with the previous msgid to hopefully save some work.
