Finds all specified files in the current directory and its sub-folders if desired.
Then removes duplicated lines, capitalizes them and sort the content.
Place the jar file in where the files to process are and with a command-line interface run java -jar sort.jar.
As input args, you can specify the extension looked for (default is "txt"), if it's recursive (default is "true") and if it capitalize the contents (default is "true").

For instance, to disable recursivity and capitalization run: java -jar sort.jar recursive false capitalize false
