+% A fast key parsing scheme originally designed for \newforeach loop.
+%
+% \quickkeys.define{<family>}[<hp>]{<list>}
+% \quickkeys.set{<family>}[<na>]{<kvlist>}
+%
+% 1. Quickly defines and set command/store keys.
+% 2. Pointers aren't used here, to speed up parsing.
+% 3. Package and class options can't be passed via quick keys.
+% 4. When defining keys, the syntax of <list> is:
+%
+% {<key1,key2,etc>}/{<default>}/{<callback>}/{<choice list>}/{<arg>}
+% ;...;
+% {<key-n>}/{<default>}/{<callback>}/{<choice list>}/{<arg>}
+%
+% Here, keys key1 and key2 will have the same default value, callback,
+% choice list and argument pattern.
+%
+% 5. The special key '.exec' will simply execute the code <default>,
+% without defining anything.
+% 6. Use .na to indicate a missing item that isn't blank.
+%
+% Example:
+% \quickkeys.define{fam}[mp@]{%
+% keya/true/\def\x##1{#1*##1}/true,false;
+% keyb;
+% keyc,keyd/aaa+bbb/\def\x##1{#1*##1*#2}/.na/#1+#2;

+% Assign arguments to keys:
+%
+% \skvassignargs[<prefixes>]{<families>}[<expansion.type>]{<keys>}{<arg>}
+%
+% 1. Valid expansion types are x0 (unexpanded), x1 (expand once),
+% x2 (expand twice), xx (expand fully). The default expansion type is
+% x0 (unexpanded).
+% 2. At set keys (not at define keys), the argument to the listed keys will
+% be expanded using the expansion type.
+% 3. The argument will be assigned whether or not a key already has been
+% defined. This allows the user to define the key later, after its
+% argument has been fixed.
+% 3. Under the macros \skvdefinekeys and \directkeys, there are equally
+% efficient handlers for assigning arguments to keys.
+%
+% Example:
+%
+% \skvassignargs[KV1,KV2]{fam1,fam2}[x1]{keya,keyb}{#1/#2}
+% \skvsetkeys[KV1]{fam2}{keya=vala/valb}
+%
+% For each prefix and family, this will define parameterless functions
+%
+% \<prefix>/<family>/key/.@x1arg.
+%
+% which will be used at setkeys to define and execute the key's callback.

+%
+% 2. Here the styles are linked with each main key. When the main key is

+% 3. Examples:
+%
+% a) The following example means that keyc and keyd are representations
+% for the actions on their right (ie, for setting 'keya=\someright,
+% keyb=\keybval') when keyc or keyd is set. The values of keya and
+% keyb will be expanded twice before the keys are set:
+%
+% .append style expand twice={keyc,keyd}/{keya=\someright,keyb=\keybval}.
+%
+% b) In the following example, #1 will be the value of keye and/or keyf
+% when they're set. The values of keye and keyf will be fully expanded
+% before they're assigned to keyc and keyd:
+%
+% .prepend style expanded={keye,keyf}/{keyc=#1,keyd=#1}

+%
+% 1. <list> has the form
+%
+% {<linkkey-1>,..,<linkkey-n>}/{<parentkey-1>,...,<parentkey-n>}
+%
+% 2. The parent key will be set (with the value of link key) whenever the
+% link key is set.
+% 3. If the link key didn't exist, it will be defined as an ordinary key
+% with the default value of the parent key. In this way, setting a
+% link key without value won't give rise to a 'no value and no default
+% error'.
+% 4. Example: Link keyb and keyc to existing keya:
+%
+% .link={keyb,keyc}/keya
+%
+% This is equivalent to:
+%
+% .style={{keyb,keyc}/keya=#1}
+%
+% This will link keyb and keyc to keya, such that when keyb and
+% keyc are set, keya too will be set with their values.

+%
+% \skvtrysetkeys[<options>]{<keyvals>}
+% .try set keys={<options>}{<keyvals>}
+%
+% Try to set a given key-value list on the paths given by the independent
+% options '.prefix/.prefixes' and '.family/.families' of \skvtrysetkeys. If
+% called within \directkeys (via the handler '.try set keys'), \skvtrysetkeys
+% will ignore the paths that are currently prevailing within \directkeys.
+% That is, within \directkeys, the handler '.try set keys' acts independent
+% of local circumstances of \directkeys.
+%
+% Save the known/found keys in the macro suggested by the option
+% <success list macro>. The user can inspect this macro to see the found
+% keys. When many families are given by the user, the success list is likely
+% to be smaller than failed list.
+%
+% Raise an error if the number of successful families is less than
+% the minimum threshold <min success>. The default value of <min success>
+% is 1. The options <min success> and <lower goal> are synonymous.
+%
+% \skvtrysetkeys is similar to \skvsetkeys*+ (ie, \skvsetkeys with the
+% options *+), but in this case we have <try> (ie, the maximum total number
+% of attempts - families to search for a given key) before backing off,
+% and <upper goal> (the maximum number of successful families in which a key
+% should be set).
+%
+% \skvtrysetkeys too will set existing preset and postset keys in the
+% given families.
+%
+% The options of \skvtrysetkeys are:
+%
+% .try:
+% The maximum number of the sum of successful and unsuccessful
+% attempts that should be made to set a key in the given SFs. The
+% default value of <try> is 12.
+% .upper goal/.max success:
+% The max. number of search families (SF) in which a given key should
+% be set/executed, if the key existed in those families. The number of
+% SFs may be more than <upper goal>, but the key may not need to be
+% executed in all of them. The default value of <upper goal> is 1.
+% .lower goal/.min success:
+% The min. number of search families (SF) in which a given key should
+% be set/executed. For any key, if <hits> is less than <lower goal>
+% an error will be flagged.
+% .prefix/.prefixes:
+% The prefixes in which the keys should be set (default=KV).
+% .families/.family:
+% Families to search.
+% .ignore keys:
+% Ignored keys. These keys will not be set even if they are found.
+% .save known keys:
+% The boolean that directs that known/found keys should be saved
+% in a macro.
+% .save known keys in/success list macro/success list:
+% The macro into which to save known keys. Each known key is
+% saved in the format: <pref>/<fam>/<key>. The user can
+% inspect this macro to see the found keys. The default macro is
+% \skvsuccesslist.
+%
+% NOTE:
+%
+% When the paths are many, the user has to be right in choosing the
+% options '.try', '.upper goal' and '.lower goal', otherwise not enough paths
+% will be searched. For example, if you want some 'keya' to be set on
+% paths KV1/fam1, KV1/fam2, KV2/fam1, KV2/fam2, and you set '.try=2' or
+% '.upper goal=2', then only 2 paths will be traversed; not the desired 4.

+% in all the listed families. But the star form of \skvprocessoptions
+% doesn't seem to make sense here, since - unlike in LaTeX2e - a star
+% suffix here would mean 'save unknown keys'. It is meaningless to seek
+% to save unknown keys when processing options. Any star (*) suffix on
+% \skvprocessoptions is, therefore, quietly ignored.
