+This is the README file for the options package.
+
+VERSION
+
+Version 1.0, December 2015
+
+SUMMARY
+
+Provices convenient key-value options for LaTeX package writers.
+
+It has a similar interface as `pgfkeys` with path options but comes with more
+built-in data types and more convenient support for families and searching.
+The main features of the `options` pckage are:
+
+* Declare your options only once: in most packages you usually need to
+ declare both a new command, and the option that sets it. 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.

+<code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\options</span>{/my/len/.new length}</code> and then use it anywhere else as

+paths (instead of families) to declare options and prevent name clashes
+between different packages. Paths are convenient for complex options,
+like <code class="code code1 language-latex lang-latex latex colorized">border/left/width</code>, and are also convenient to specify searches.

+<p class="p noindent">Defining options is very easy. As an example, we will make an <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\mybox</span></code> command
+that takes named options. Our goal is that the user can invoke <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\mybox</span></code> like:
+</p>
+<pre class="para-block pre-indented language-latex lang-latex latex colorized" style="display:block"><code><span style="color:navy">\mybox</span>{padding=<span class="constant" style="color:navy">1ex</span>, border/width=<span class="constant" style="color:navy">0.4pt</span>, font/style=italic}{text}</code></pre><h3 id="sec-an-example" class="h2 sans-serif" data-heading-depth="2" style="display:block;font-weight:normal"><span class="heading-before"><span class="heading-label">2.1</span>.&#8194;</span>An example</h3>
+<p class="p noindent">We can define the options for our <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\mybox</span></code> command as:
+</p>
+<div class="mathdefs input-mathdefs" style="line-adjust:0"></div>
+<pre class="para-block pre-fenced pre-fenced3 language-latex lang-latex latex colorized" style="display:block;line-adjust:0;text-indent:0pt"><code><span style="color:navy">\options</span>{
+ /mybox/.new family,
+ /mybox/padding/.new length = <span style="color:navy">\fboxsep</span>,
+ /mybox/border/width/.new length = <span style="color:navy">\fboxrule</span> * 2,
+ /mybox/border/color/.new color,
+ /mybox/font/style/.new choice = {normal,italic,small-caps},
+}</code></pre>
+<p class="p noindent">The options are all specified as a <em class="em-low1">path</em> where names that start with a
+dot, like <code class="code code1 language-latex lang-latex latex colorized">.new length</code> are called <em class="em-low1">handlers</em>. In this case, the handlers
+create the options for our box command. To parse the options passed by
+the user, we use the same <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\options</span></code> command:
+</p>
+<div class="mathdefs input-mathdefs" style="line-adjust:0"></div>
+<pre class="para-block pre-fenced pre-fenced3 language-latex lang-latex latex colorized" style="display:block;line-adjust:0;text-indent:0pt"><code><span style="color:navy">\newcommand</span><span style="color:navy">\mybox</span>[2]{<span style="color:darkgreen">%</span>

+ }<span style="color:darkgreen">%</span>
+}</code></pre>
+<p class="p noindent">Here we start the option list with <code class="code code1 language-latex lang-latex latex colorized">/mybox</code> which makes that the default
+path (because it was declared with <code class="code code1 language-latex lang-latex latex colorized">.new family</code>) so the user can give
+relative option names instead of prefixing all options with <code class="code code1 language-latex lang-latex latex colorized">/mybox/</code>.
+Options are always set local to the current group.
+</p>
+<p class="p indent">Finally, we can use <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\option</span>{<span class="code-escaped"><span class="param serif" style="font-size:120%">&#9001;<em class="em-star1">option</em>&#9002;</span></span>}</code> to get the value of an option.
+This command expands directly to the command name (i.e. <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\optk@</span><span class="code-escaped"><span class="param serif" style="font-size:120%">&#9001;<em class="em-star1">option</em>&#9002;</span></span></code>)
+and is very efficient. So, our implementation for displaying our box may
+look like:

+<p class="p noindent">Another improvement is in our choice definition for the font. Instead of using

+<p class="p noindent">The option paths are mainly used to prevent name clashes between different
+packages but they can also be used for searches. In particular, we can
+specify for any path that if a sub-path cannot be found, we should look
+under another path. Suppose we define a new <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\fancymybox</span></code> command that
+takes some extra options. In that case, we would like to re-use the
+<code class="code code1 language-latex lang-latex latex colorized">/mybox</code> options and look for any undefined options under <code class="code code1 language-latex lang-latex latex colorized">/mybox</code> instead:

+}</code></pre>
+<p class="p noindent">Note how the <code class="code code1 language-latex lang-latex latex colorized">rounded</code> style takes an argument which is defaulted to <code class="code code1 language-latex lang-latex latex colorized"><span class="constant" style="color:navy">5pt</span></code>.
+In the <code class="code code1 language-latex lang-latex latex colorized">.new family</code> declaration, we can provide a list of search paths: here we just
+gave <code class="code code1 language-latex lang-latex latex colorized">/mybox</code> such that any options not found under <code class="code code1 language-latex lang-latex latex colorized">/fancymybox</code> will be looked up

+<p class="p noindent">In the previous sample, <code class="code code1 language-latex lang-latex latex colorized">/mybox/border/normal</code> is invoked. In general, we
+can add comma separated search paths either in a <code class="code code1 language-latex lang-latex latex colorized">.new family</code> declaration
+or using the <code class="code code1 language-latex lang-latex latex colorized">.search also</code> handler. Search paths can be added to any path
+and will apply recursively. For example, if we set:
+</p>
+<div class="mathdefs input-mathdefs" style="line-adjust:0"></div>
+<pre class="para-block pre-fenced pre-fenced3 language-latex lang-latex latex colorized" style="display:block;line-adjust:0;text-indent:0pt"><code><span style="color:navy">\options</span>{

+<p class="p noindent">Note that the <code class="code code1 language-latex lang-latex latex colorized">options</code> package will even search if an absolute path

+comma used to separate the options. For convenience, the <code class="code code1 language-latex lang-latex latex colorized">new choice</code> handler also

+The ordinal is a number and can be tested efficiently using
+<code class="code code1 language-latex lang-latex latex colorized">ifcase</code> and <code class="code code1 language-latex lang-latex latex colorized">ifnum</code>. For example:

+<p class="p noindent">There are various kinds of handlers:

+<p class="p noindent">Handlers are also used to define the standard data types and can be used
+to define new data types yourself. Here is for example how the <code class="code code1 language-latex lang-latex latex colorized">value</code>
+data type is defined:
+</p>
+<pre class="para-block pre-fenced pre-fenced3 language-latex lang-latex latex colorized" style="display:block"><code><span style="color:navy">\option</span>{
+ /handlers/new value/.new handler = []<span style="color:navy">\optionsalso</span>{<span style="color:darkgreen">%</span>
+ <span class="constant" style="color:navy">#1</span>/.new cmd = <span style="color:navy">\option@set</span>{<span class="constant" style="color:navy">#1</span>}{<span class="constant" style="color:navy">##1</span>},

+ <span class="constant" style="color:navy">#1</span>/.initial = {<span class="constant" style="color:navy">#2</span>},
+ },
+}</code></pre>
+<p class="p noindent para-continued">The <code class="code code1 language-latex lang-latex latex colorized">.new handler</code> receives the current path (<code class="code code1 language-latex lang-latex latex colorized"><span class="constant" style="color:navy">#1</span></code>) and the initial value (<code class="code code1 language-latex lang-latex latex colorized"><span class="constant" style="color:navy">#2</span></code>).
+The default value provided at definition time is empty (<code class="code code1 language-latex lang-latex latex colorized">[]</code>). When a user
+defines a new value, we simply set more options based on the path. When the
+defined option is set, the <code class="code code1 language-latex lang-latex latex colorized">.new cmd</code> is called with the argument (<code class="code code1 language-latex lang-latex latex colorized"><span class="constant" style="color:navy">##1</span></code>) and
+we use that set the actual option value directly: <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\option@set</span>{<span class="constant" style="color:navy">#1</span>}{<span class="constant" style="color:navy">##1</span>}</code>.
+Usually, we do some additional processing here, for example, for choice values
+we would check if the choice is valid.
+</p><h3 id="sec-special" class="h2 sans-serif" data-heading-depth="2" style="display:block;font-weight:normal"><span class="heading-before"><span class="heading-label">6.3</span>.&#8194;</span>Single option values</h3>
+<p class="p noindent">Finally, we can also specify handlers that are invoked when the option name
+starts with special character. This allows you to handle, say, a quoted value
+like <code class="code code1 language-latex lang-latex latex colorized">&quot;Georgia&quot;</code> as a shorthand for <code class="code code1 language-latex lang-latex latex colorized">/font/family=Georgia</code>. As an example, we
+will handle options that start with a bang (<code class="code code1 language-latex lang-latex latex colorized">!</code>) as an HTML color.
