/** This class lets you parse, edit or create files containing groups of key-value pairs, which we call key files
 * for lack of a better name. Several freedesktop.org specifications use key files now, e.g the Desktop Entry
 * Specification and the Icon Theme Specification.
 *
 * The syntax of key files is described in detail in the Desktop Entry Specification, here is a quick summary: Key
 * files consists of groups of key-value pairs, interspersed with comments.
 *
 * @code
 * # this is just an example
 * # there can be comments before the first group
 *
 * [First Group]
 *
 * Name=Key File Example\tthis value shows\nescaping
 *
 * # localized strings are stored in multiple key-value pairs
 * Welcome=Hello
 * Welcome[de]=Hallo
 * Welcome[fr]=Bonjour
 * Welcome[it]=Ciao
 *
 * [Another Group]
 *
 * Numbers=2;20;-200;0
 *
 * Booleans=true;false;true;true
 * @endcode
 *
 * Lines beginning with a '#' and blank lines are considered comments.
 *
 * Groups are started by a header line containing the group name enclosed in '[' and ']', and ended implicitly by
 * the start of the next group or the end of the file. Each key-value pair must be contained in a group.
 *
 * Key-value pairs generally have the form key=value, with the exception of localized strings, which have the form
 * key[locale]=value. Space before and after the '=' character are ignored. Newline, tab, carriage return and
 * backslash characters in value are escaped as \\n, \\t, \\r, and \\\\, respectively. To preserve leading spaces in
 * values, these can also be escaped as \\s.
 *
 * Key files can store strings (possibly with localized variants), integers, booleans and lists of these. Lists are
 * separated by a separator character, typically ';' or ','. To use the list separator character in a value in a
 * list, it has to be escaped by prefixing it with a backslash.
 *
 * This syntax is obviously inspired by the .ini files commonly met on Windows, but there are some important
 * differences:
 * - .ini files use the ';' character to begin comments, key files use the '#' character.
 * - Key files allow only comments before the first group.
 * - Key files are always encoded in UTF-8.
 * - Key and Group names are case-sensitive, for example a group called [GROUP] is a different group from [group].
 *
 * Note that in contrast to the Desktop Entry Specification, groups in key files may contain the same key multiple
 * times; the last entry wins. Key files may also contain multiple groups with the same name; they are merged
 * together. Another difference is that keys and group names in key files are not restricted to ASCII characters.
