# All available hdf language files are parsed for creating pot (po-template) files.
|
|
# All existing po-file are merged with these templates to remove obsolete msgids.
|
|
# Additionally every msgstr of the english original is set to the value of the
|
|
# respective msgid.
|
|
# All resulting po files are chmod'ed to 0666 - this is useful if you locally use
|
|
# services like pootle.
|
|
# If there were no changes besides the "POT-Creation-Date" header, then the file
|
|
# is reverted via svn to avoid unnecessary commits.
