# Example 1.1:  
#   Variation 1:  add a method 'handle_errors_and_help' to autoparse, check, and augment ARGV
module Example extend OptiFlag::Flagset
  flag "dir"
  flag "log"
  flag "username"
  flag "password"

  handle_errors_and_help

# Some code to _use_ the values
puts "User has input:#{ ARGV.flag_value.dir  } for dir"
puts "User has input:#{ ARGV.flag_value.log  } for log"
puts "User has input:#{ ARGV.flag_value.username  } for username"
puts "User has input:#{ ARGV.flag_value.password  } for password"

puts " The variable ARGV has been extend to hold the return variables."

# Try the following inputs
## Breaks:
#h#   ruby example_1_1.rb
## Works:
#h#   ruby example_1_1.rb -log logdirectory -dir directory -username me -password fluffy
#   ruby example_1_1.rb --log logdirectory --dir directory --username me --password fluffy
