In the + `options` package you declare the option just once. For example, + + \options{/my/len/.new length} + + and then use it anywhere else as + + \option{/my/len} + +* _Use paths for keys_: just like `pgfkeys`, the `options` package uses + paths (instead of families) to declare options and prevent name clashes + between different packages. Paths are convenient for complex options, + like `border/left/width`, and are also convenient to specify searches. + +* _Many built-in data types_: the `options` library comes with many + useful data types like `choice`, `list`, `toggle`, `num`, `dim`, + `length`, `glue`, commands, and plain values, and it is easy to add + your own. Also you can hook into existing definitions like an `if` or `counter`. + +* _Value options_: You can define value-only options that start with a + special character, like `"Georgia"` for a font option, or + `!8080FF` for a color option. + +* _Convenient searches_: you can specify paths that should be searched + from other paths and redirect even from absolute paths. For complex + packages this is very useful to inherit common options. + +* _Easy filtering_: it is easy to collect unknown options and process + them later. Combined with the search mechanism this makes it easy to + do custom processing. + +* _It is fast_: for simple user options, the &options; package is a bit + faster than `pgfkeys` and if searches or filters are involved it is + usually about twice as fast as `pgfkeys` (and about six times faster + as `xkeyval`). + +* _Handles class and package options_: use the same option declarations + to handle the options passed to a class or package. + +LICENSE + +Copyright (c) 2015 Daan Leijen. + +This software is author-maintained.
