- -b, --boolean get a boolean
+ --yes get a boolean
+ -D, --no-doubt begins with 'no-'
+ -B, --no-fear be brave
+ -b, --boolean increment by one
-4, --or4 bitwise-or boolean with ...0100
+ --neg-or4 same as --no-or4

-j <n> get a integer, too
--set23 set integer to 23
-t <time> get timestamp of <time>
-L, --length <str> get length of <str>
+ -F, --file <file> set file to <file>
String options
-s, --string <string>
--st <st> get another string (pervert ordering)
-o <str> get another string
--default-string set string to default
+ --list <str> add str to list
Magic arguments
--quux means --quux
+ -NUM set integer to NUM
+ + same as -b
