#flags
This is a library to help developers build neatly formatted and easy to understand command line parsing.
#example
This example can be run with the command java FlagsStarter --help which will print the command line help, or java FlagsStarter --text HelloWorld --times 2 --active true which will print "HelloWorld" 2 times.
