[Simple Values]
key=value
spaces in keys=allowed
spaces in values=allowed as well
spaces around the delimiter = obviously
you can also use : to delimit keys from values

[All Values Are Strings]
values like this: 1000000
or this: 3.14159265359
are they treated as numbers? : no
integers, floats and booleans are held as: strings
can use the API to get converted values directly: true

[Multiline Values]
[No Values]
key_without_value
empty string value here =

[You can use comments]
# like this
; or this

# By default only in an empty line.
# Inline comments can be harmful because they prevent users
# from using the delimiting characters as parts of values.
# That being said, this can be customized.

     [Sections Can Be Indented]
         can_values_be_as_well = True
         does_that_mean_anything_special = False
         purpose = formatting for readability
         # Did I mention we can indent comments, too?";
	foreach(item; parseINI(data)) {
		writeln("[*", text(item), "*]");
	}
