21 * that you need and places it into tables and things for easy access.
22 * There are three types of input that data can come from, StandardInput,
23 * CommandLine, and Cookies. StandardInput is when you get formdata in
24 * multi-part forms, Cookies should usually be cookies that you set, and
25 * command line is everything after the question mark in the URL.
26 * This also contains some simple helpers for putting templated data into the

20 * A simple yet flexable hash-table. This uses several tricks to help ensure
21 * that the table is always running at maximum efficiency. You no longer have
22 * to specify a "danger fill level" when more space is needed a rehash is
23 * automatically trigered. Deleting elements is fully supported, as well as
24 * duplicate elements. To work with and allow duplicates simple construct your
25 * HashTable the way you normally would, but when deleting or getting elements
26 * you can specify a skip value. This effectively allows you to treat elements
27 * with duplicate ID's as though they were in a zero-based array. The first
28 * element inserted with a given ID would be at skip zero, the next at skip 1
29 * and so on. This allows you to quickly search for elements with duplicate
30 * names, just stop when you get a null for a skip number, i.e.
31 * <pre>
32 * for( int j = 0;; j++ )
33 * {
34 * void *pData = hash.get( myID, j );
35 * if( !pData ) break;
36 * // Do something interesting with pData
37 * }
38 * </pre>
39 * There are new features in this HashTable that also allow for memory saving
40 * when dealing with systems where many elements are being deleted from the
41 * table. In those cases the elements deleted cannot be simply deleted, instead
42 * they have to be marked as deleted and hidden from the user, but maintained in
43 * the table so that future hashing operations don't fail. When rehashing
44 * occurs all elements marked as deleted are quietly removed. In these cases,
45 * if the number of deleted items would free enough space in the table for the
46 * table to be used efficiently without resizing, it is left the same size and
47 * rehashing is performed effectively in place, allowing the deleted items to
48 * be removed.

19 * <li>%l - Loglevel (numerical)</li>
20 * <li>%f - Filename</li>

8 * Implements xml writing in the XML standard format. Also allows you to
9 * break that format and auto-indent your exported xml data for ease of
10 * reading. The auto-indenting will only be applied to sections that
11 * have no content of their own already. This means that except for
12 * whitespace all of your data will be preserved perfectly.
13 * You can create an XmlWriter object around a file, or access the static
14 * write function directly and just hand it a filename and a root XmlNode.
15 * When using an XmlWriter object the interface is identicle to that of
16 * the XmlDocument class, so reference that class for API info. However
17 * when the initial (or root) node is closed, and the document is finished
18 * the file will be created and written to automatically. The user can
19 * check to see if this is actually true by calling the isFinished
20 * function in the XmlDocument class.

11 * have no content of their own already. This means that except for
12 * whitespace all of your data will be preserved perfectly.
13 * You can create an XmlWriter object around a file, or access the static
14 * write function directly and just hand it a filename and a root XmlNode.
15 * When using an XmlWriter object the interface is identicle to that of
16 * the XmlDocument class, so reference that class for API info. However
17 * when the initial (or root) node is closed, and the document is finished
18 * the file will be created and written to automatically. The user can
19 * check to see if this is actually true by calling the isFinished
20 * function in the XmlDocument class.
