• pcArray & pcList: Well, they are actually the same thing, just a little redesigned for more logical use. For practical use see tree, Hashlist, strarray units.
• pcHashList: Classic Hashing Class with a little 'Cherry' on top. It can use CRC32 Encoding Checking and MD5 Byte Hashing. For MD5 Copyights read included MD5 Readme file.
• pcQueue & pcStack: Classic Queue and Stack, just the way you read it in those old algorith books
• pcTree: The most robust part of the pack, real tree system with structure saving capabilities. +a small addon of a simplest Binary Tree, with NO methods, only one constructor :)
• pcStrArray: An example of what you can do with the pcArray. Using this method you can store your custom data easily.
  And a little bonus for the desert:
• DynamicArray: A little something to show you that making real Dynamic Arrays could be a rather simple task
• pcRandomString: One function that will generate a Random String (as you guessed). Usefull for creating temp files with unique names.

Several TStream descendant classes that provide additional stream functionality

• A TStream derived class which can wrap another TStream - this is useful as a base class for filters to wrap round existing stream classes
• A set of stream wrappers that simplify writing data to a resource file - one class handles the resource file structure (including headers) while another handles the format of individual resources within the file.
• New for release 2: a set of classes that wrap existing streams and provide an IStream interface to them - like Delphi's undocumented TStreamAdapter - plus a class that provides a IStream interface to any file.

Several demo programs are included.
