-module flag for command-line flag parsing
-
-- parsing flags like '--flag' or '--stuff=things' or '--things stuff'
-- handles bool, int, float and string args
-- is able to print usage
-- handled unknown arguments as error
+The `flag` module helps command-line flag parsing.
+Main features are:
+- parses flags like `-f` or '--flag' or '--stuff=things' or '--things stuff'.
+- handles bool, int, float and string args.
+- can print usage information listing all the declrared flags.
+- handles unknown arguments as error.
 
 Usage example:
 
- ```v
- module main
+```v
+module main
 
- import os
- import flag
+import os
+import flag
 
- fn main() {
- 	mut fp := flag.new_flag_parser(os.args)
- 	fp.application('flag_example_tool')
- 	fp.version('v0.0.0')
- 	fp.description('This tool is only designed to show how the flag lib is working')
-
- 	fp.skip_executable()
-
- 	an_int := fp.int('an_int', 0, 0o666, 'some int to define 0o666 is default')
- 	a_bool := fp.bool('a_bool', 0, false, 'some \'real\' flag')
- 	a_float := fp.float('a_float', 0, 1.0, 'also floats')
- 	a_string := fp.string('a_string', `a`, 'no text', 'finally, some text with "a" an abbreviation')
-
- 	additional_args := fp.finalize() or {
- 		eprintln(err)
- 		println(fp.usage())
- 		return
- 	}
-
- 	println('
- 		  an_int: $an_int
- 		  a_bool: $a_bool
- 		 a_float: $a_float
- 		a_string: \'$a_string\'
- 	')
- 	println(additional_args.join_lines())
- }
- ```
