+ * @title: Key-value file parser
+ * @short_description: parses .ini-like config files
+ *
+ * #GKeyFile 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](http://freedesktop.org/Standards/desktop-entry-spec)
+ * and the
+ * [Icon Theme Specification](http://freedesktop.org/Standards/icon-theme-spec).
+ *
+ * The syntax of key files is described in detail in the
+ * [Desktop Entry Specification](http://freedesktop.org/Standards/desktop-entry-spec),
+ * here is a quick summary: Key files
+ * consists of groups of key-value pairs, interspersed with comments.
+ *
+ * |[
+ * # 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_FR]=Bonjour
+ * Welcome[it]=Ciao
+ * Welcome[be@latin]=Hello
+ *
+ * [Another Group]
+ *
+ * Numbers=2;20;-200;0
+ *
+ * Booleans=true;false;true;true
+ * ]|
+ *
+ * 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`, with a locale identifier of the
+ * form `lang_COUNTRY@MODIFIER` where `COUNTRY` and `MODIFIER`
+ * are optional.
+ * 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 do not allow for ungrouped keys meaning only
+ * comments can precede 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 from [group].
+ *
+ * - .ini files don't have a strongly typed boolean entry type,
+ * they only have GetProfileInt(). In key files, only
+ * true and false (in lower case) are allowed.
+ *
+ * Note that in contrast to the
+ * [Desktop Entry Specification](http://freedesktop.org/Standards/desktop-entry-spec),
+ * 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.
