/*=========================================================================*\
* Auxiliar routines for class hierarchy manipulation
* LuaSocket toolkit (but completely independent of other LuaSocket modules)
*
* A LuaSocket class is a name associated with Lua metatables. A LuaSocket
* group is a name associated with a class. A class can belong to any number
* of groups. This module provides the functionality to:
*
* - create new classes
* - add classes to groups
* - set the class of objects
* - check if an object belongs to a given class or group
* - get the userdata associated to objects
* - print objects in a pretty way
*
* LuaSocket class names follow the convention <module>{<class>}. Modules
* can define any number of classes and groups. The module tcp.c, for
* example, defines the classes tcp{master}, tcp{client} and tcp{server} and
* the groups tcp{client,server} and tcp{any}. Module functions can then
* perform type-checking on their arguments by either class or group.
*
* LuaSocket metatables define the __index metamethod as being a table. This
* table has one field for each method supported by the class, and a field
* "class" with the class name.
*
* The mapping from class name to the corresponding metatable and the
* reverse mapping are done using lauxlib.

/*=========================================================================*\
* Exception control
* LuaSocket toolkit (but completely independent from other modules)
*
* This provides support for simple exceptions in Lua. During the
* development of the HTTP/FTP/SMTP support, it became aparent that
* error checking was taking a substantial amount of the coding. These
* function greatly simplify the task of checking errors.
*
* The main idea is that functions should return nil as its first return
* value when it finds an error, and return an error message (or value)
* following nil. In case of success, as long as the first value is not nil,
* the other values don't matter.
*
* The idea is to nest function calls with the "try" function. This function
* checks the first value, and calls "error" on the second if the first is
* nil. Otherwise, it returns all values it received.
*
* The protect function returns a new function that behaves exactly like the
* function it receives, but the new function doesn't throw exceptions: it
* returns nil followed by the error message instead.
*
* With these two function, it's easy to write functions that throw
* exceptions on error, but that don't interrupt the user script.

*
* This library is part of an effort to progressively increase the network
* connectivity of the Lua language. The Lua interface to networking
* functions follows the Sockets API closely, trying to simplify all tasks
* involved in setting up both client and server connections. The provided
* IO routines, however, follow the Lua style, being very similar to the
* standard Lua read and write functions.
