+/**
+ * General filename and filepath manipulation utilities.
+ * <p>
+ * When dealing with filenames you can hit problems when moving from a Windows
+ * based development machine to a Unix based production machine.
+ * This class aims to help avoid those problems.
+ * <p>
+ * <b>NOTE</b>: You may be able to avoid using this class entirely simply by
+ * using JDK {@link java.io.File File} objects and the two argument constructor
+ * {@link java.io.File#File(java.io.File, java.lang.String) File(File,String)}.
+ * <p>
+ * Most methods on this class are designed to work the same on both Unix and Windows.
+ * Those that don't include 'System', 'Unix' or 'Windows' in their name.
+ * <p>
+ * Most methods recognise both separators (forward and back), and both
+ * sets of prefixes. See the javadoc of each method for details.
+ * <p>
+ * This class defines six components within a filename
+ * (example C:\dev\project\file.txt):
+ * <ul>
+ * <li>the prefix - C:\</li>
+ * <li>the path - dev\project\</li>
+ * <li>the full path - C:\dev\project\</li>
+ * <li>the name - file.txt</li>
+ * <li>the base name - file</li>
+ * <li>the extension - txt</li>
+ * </ul>
+ * Note that this class works best if directory filenames end with a separator.
+ * If you omit the last separator, it is impossible to determine if the filename
+ * corresponds to a file or a directory. As a result, we have chosen to say
+ * it corresponds to a file.
+ * <p>
+ * This class only supports Unix and Windows style names.
+ * Prefixes are matched as follows:
+ * <pre>
+ * Windows:
+ * a\b\c.txt           --> ""          --> relative
+ * \a\b\c.txt          --> "\"         --> current drive absolute
+ * C:a\b\c.txt         --> "C:"        --> drive relative
+ * C:\a\b\c.txt        --> "C:\"       --> absolute
+ * \\server\a\b\c.txt  --> "\\server\" --> UNC
+ *
+ * Unix:
+ * a/b/c.txt           --> ""          --> relative
+ * /a/b/c.txt          --> "/"         --> absolute
+ * ~/a/b/c.txt         --> "~/"        --> current user
+ * ~                   --> "~/"        --> current user (slash added)
+ * ~user/a/b/c.txt     --> "~user/"    --> named user
+ * ~user               --> "~user/"    --> named user (slash added)
+ * </pre>
+ * Both prefix styles are matched always, irrespective of the machine that you are
+ * currently running on.
+ * <p>
+ * Origin of code: Excalibur, Alexandria, Tomcat, Commons-Utils.

+
+/// A composable, [Future]-based library for making HTTP requests.
+///
+/// The easiest way to use this library is via the top-level functions. They
+/// allow you to make individual HTTP requests with minimal hassle:
+///
+///     import 'package:http/http.dart' as http;
+///
+///     var url = "http://example.com/whatsit/create";
+///     http.post(url, fields: {"name": "doodle", "color": "blue"})
+///         .then((response) {
+///       print("Response status: ${response.statusCode}");
+///       print("Response body: ${response.body}");
+///     });
+///
+///     http.read("http://example.com/foobar.txt").then(print);
+///
+/// If you're making multiple requests to the same server, you can keep open a
+/// persistent connection by using a [Client] rather than making one-off
+/// requests. If you do this, make sure to close the client when you're done:
+///
+///     var client = new http.Client();
+///     client.post(
+///         "http://example.com/whatsit/create",
+///         fields: {"name": "doodle", "color": "blue"})
+///       .chain((response) => client.get(response.bodyFields['uri']))
+///       .transform((response) => print(response.body))
+///       .onComplete((_) => client.close());
+///
+/// You can also exert more fine-grained control over your requests and
+/// responses by creating [Request] or [StreamedRequest] objects yourself and
+/// passing them to [Client.send].
+///
+/// This package is designed to be composable. This makes it easy for external
+/// libraries to work with one another to add behavior to it. Libraries wishing
+/// to add behavior should create a subclass of [BaseClient] that wraps another
+/// [BaseClient] and adds the desired behavior:
+///
+///     class UserAgentClient extends http.BaseClient {
+///       final String userAgent;
+///       final HttpClient _inner;
+///
+///       UserAgentClient(this.userAgent, this._inner);
+///
+///       Future<StreamedResponse> send(BaseRequest request) {
+///         request.headers[HttpHeaders.USER_AGENT] = userAgent;
+///         return _inner.send(request);
+///       }
+///     }
+///
+/// In turn, libraries using [Client] should take a [BaseClient] so that the
+/// decorated clients can be used transparently.
