Description

None of the options -h, --h, -help or --help works. Since these are pretty common when working with command line tools, it would be nice to have them in Alk as well. Here's what I tried:

andrei@pc:~/work/temp/java-semantics$ ./bin/alki.sh -help
java.io.FileNotFoundException: -help (No such file or directory)
	at java.base/java.io.FileInputStream.open0(Native Method)
