+/**
+ * A JSONArray is an ordered sequence of values. Its external text form is a
+ * string wrapped in square brackets with commas separating the values. The
+ * internal form is an object having <code>get</code> and <code>opt</code>
+ * methods for accessing the values by index, and <code>put</code> methods for
+ * adding or replacing values. The values can be any of these types:
+ * <code>Boolean</code>, <code>JSONArray</code>, <code>JSONObject</code>,
+ * <code>Number</code>, <code>String</code>, or the
+ * <code>JSONObject.NULL object</code>.
+ * <p>
+ * The constructor can convert a JSON text into a Java object. The
+ * <code>toString</code> method converts to JSON text.
+ * <p>
+ * A <code>get</code> method returns a value if one can be found, and throws an
+ * exception if one cannot be found. An <code>opt</code> method returns a
+ * default value instead of throwing an exception, and so is useful for
+ * obtaining optional values.
+ * <p>
+ * The generic <code>get()</code> and <code>opt()</code> methods return an
+ * object which you can cast or query for type. There are also typed
+ * <code>get</code> and <code>opt</code> methods that do type checking and type
+ * coersion for you.
+ * <p>
+ * The texts produced by the <code>toString</code> methods strictly conform to
+ * JSON syntax rules. The constructors are more forgiving in the texts they will
+ * accept:
+ * <ul>
+ * <li>An extra <code>,</code> <small>(comma)</small> may appear just
+ * before the closing bracket.</li>
+ * <li>The <code>null</code> value will be inserted when there
+ * is <code>,</code> <small>(comma)</small> elision.</li>
+ * <li>Strings may be quoted with <code>'</code> <small>(single
+ * quote)</small>.</li>
+ * <li>Strings do not need to be quoted at all if they do not begin with a quote
+ * or single quote, and if they do not contain leading or trailing spaces,
+ * and if they do not contain any of these characters:
+ * <code>{ } [ ] / \ : , = ; #</code> and if they do not look like numbers
+ * and if they are not the reserved words <code>true</code>,
+ * <code>false</code>, or <code>null</code>.</li>
+ * <li>Values can be separated by <code>;</code> <small>(semicolon)</small> as
+ * well as by <code>,</code> <small>(comma)</small>.</li>
+ * <li>Numbers may have the <code>0-</code> <small>(octal)</small> or
+ * <code>0x-</code> <small>(hex)</small> prefix.</li>
+ * <li>Comments written in the slashshlash, slashstar, and hash conventions
+ * will be ignored.</li>
+ * </ul>

+/**
+ * A JSONObject is an unordered collection of name/value pairs. Its
+ * external form is a string wrapped in curly braces with colons between the
+ * names and values, and commas between the values and names. The internal form
+ * is an object having <code>get</code> and <code>opt</code> methods for
+ * accessing the values by name, and <code>put</code> methods for adding or
+ * replacing values by name. The values can be any of these types:
+ * <code>Boolean</code>, <code>JSONArray</code>, <code>JSONObject</code>,
+ * <code>Number</code>, <code>String</code>, or the <code>JSONObject.NULL</code>
+ * object. A JSONObject constructor can be used to convert an external form
+ * JSON text into an internal form whose values can be retrieved with the
+ * <code>get</code> and <code>opt</code> methods, or to convert values into a
+ * JSON text using the <code>put</code> and <code>toString</code> methods.
+ * A <code>get</code> method returns a value if one can be found, and throws an
+ * exception if one cannot be found. An <code>opt</code> method returns a
+ * default value instead of throwing an exception, and so is useful for
+ * obtaining optional values.
+ * <p>
+ * The generic <code>get()</code> and <code>opt()</code> methods return an
+ * object, which you can cast or query for type. There are also typed
+ * <code>get</code> and <code>opt</code> methods that do type checking and type
+ * coersion for you.
+ * <p>
+ * The <code>put</code> methods adds values to an object. For example, <pre>
+ * myString = new JSONObject().put("JSON", "Hello, World!").toString();</pre>
+ * produces the string <code>{"JSON": "Hello, World"}</code>.
+ * <p>
+ * The texts produced by the <code>toString</code> methods strictly conform to
+ * the JSON sysntax rules.
+ * The constructors are more forgiving in the texts they will accept:
+ * <ul>
+ * <li>An extra <code>,</code> <small>(comma)</small> may appear just
+ * before the closing brace.</li>
+ * <li>Strings may be quoted with <code>'</code> <small>(single
+ * quote)</small>.</li>
+ * <li>Strings do not need to be quoted at all if they do not begin with a quote
+ * or single quote, and if they do not contain leading or trailing spaces,
+ * and if they do not contain any of these characters:
+ * <code>{ } [ ] / \ : , = ; #</code> and if they do not look like numbers
+ * and if they are not the reserved words <code>true</code>,
+ * <code>false</code>, or <code>null</code>.</li>
+ * <li>Keys can be followed by <code>=</code> or <code>=></code> as well as
+ * by <code>:</code>.</li>
+ * <li>Values can be followed by <code>;</code> <small>(semicolon)</small> as
+ * well as by <code>,</code> <small>(comma)</small>.</li>
+ * <li>Numbers may have the <code>0-</code> <small>(octal)</small> or
+ * <code>0x-</code> <small>(hex)</small> prefix.</li>
+ * <li>Comments written in the slashshlash, slashstar, and hash conventions
+ * will be ignored.</li>

You think that by now after all the emails to James on this I would have
figured it out. It's an Subclipse idiosyncrasy that gives me the
illusion that I already called Add to Repo but I didn't. Last time I
promise.

I totally agree so I have moved the code around, but I need help with
the glue code ;) hint, hint.

First off, any time you see yourself making several commits right in
succession that all have the same log message, you should probably be
thinking about why they weren't done in one commit ;-)
Second, wouldn't it be more consistent to put the source to the JSON
classes in the dependencies directory? I'm not overly fond of having
source that we didn't generate and that's outside the org.apache.*
namespace in the extensions/ subdirectory, keeping it in dependencies
should help to remind people that this is code that was not produced
by the project and that needs to be treated somewhat specially (i.e.
if we someday need to update to a new version of the Apache License we
can't just update those files to them, they're under a specific
version and we have no right to change that...).
This would probably require some build glue to correctly create a
separate dependency jar, etc, but I think it's a worthwhile thing to
hold the release for.
Thoughts?
