# This program collects all upstream translations defined in
# configuration and merges them together.

# If you want to use po files for completing of translations, you can remove --no-fuzzy-matching.
# It will run much slower, but you could start with fuzzy matches.

# Debug mode. Set to true if you want to keep working directories.
DEBUG=false
# Incremental mode. With exception of bootstrapping or resetting the memory, it should be true.
# Non-incremental update cannot process a single package.
# FIXME: The incremental mode does not drop obsolete packages. You
# need to delete them manually afterwards using time stamp.
INCREMENTAL=true
# Set to false to generate only pot files, true to collect po files.
COLLECT_UPSTREAM=true
# Number of CPUs. When > 1, then parallel processing of more po files is possible.
