+/*=========================================================================*\
+* 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.
