- * Create all the hierarchy files which are used for looking up hierarchichal trees.
- * This script will search the Solr index and create the files needed so they don't
- * need to be built at runtime. If this script is run after every index, the caching
- * time for hierarchy trees can be set to -1 so that trees are always assumed to be
- * up to date.
+ * This tool allows to compare and synchronize language files for VuFind2.
+ * You can either run it as CLI-tool with output on STDOUT to check whether
+ * language files are out of sync (default) or synchronize language files
+ * automatically by writing the missing lines into the .ini files.
