-  This file contains the nsStr data structure.
-  This general purpose buffer management class is used as the basis for our strings.
-  It's benefits include:
-    1. An efficient set of library style functions for manipulating nsStrs
-    2. Support for 1 and 2 byte character strings (which can easily be increased to n)
-    3. Unicode awareness and interoperability.

-  MODULE NOTES:
-
-    1. There are two philosophies to building string classes:
-        A. Hide the underlying buffer & offer API's allow indirect iteration
-        B. Reveal underlying buffer, risk corruption, but gain performance
-        
-       We chose the option B for performance reasons. 
-
-    2  Our internal buffer always holds capacity+1 bytes.
-
-    The nsStr struct is a simple structure (no methods) that contains
-    the necessary info to be described as a string. This simple struct
-    is manipulated by the static methods provided in this class. 
-    (Which effectively makes this a library that works on structs).
-
-    There are also object-based versions called nsString and nsAutoString
-    which use nsStr but makes it look at feel like an object. 
-
- ***********************************************************************/
-
-/***********************************************************************
-  ASSUMPTIONS:
-
-    1. nsStrings and nsAutoString are always null terminated. However,
-       since it maintains a length byte, you can store NULL's inside
-       the string. Just be careful passing such buffers to 3rd party
-       API's that assume that NULL always terminate the buffer.
-
-    2. nsCStrings can be upsampled into nsString without data loss
-
-    3. Char searching is faster than string searching. Use char interfaces
-       if your needs will allow it.
-
-    4. It's easy to use the stack for nsAutostring buffer storage (fast too!).
-       See the CBufDescriptor class in this file.
-
-    5. If you don't provide the optional count argument to Append() and Insert(),
-       the method will assume that the given buffer is terminated by the first
-       NULL it encounters.
-
-    6. Downsampling from nsString to nsCString can be lossy -- avoid it if possible!
-
-    7. Calls to ToNewCString() and ToNewUnicode() should be matched with calls to nsMemory::Free().
-
- ***********************************************************************/

-
-/**********************************************************************************
-  
- AND NOW FOR SOME GENERAL DOCUMENTATION ON STRING USAGE...
-
-    The fundamental datatype in the string library is nsStr. It's a structure that
-    provides the buffer storage and meta-info. It also provides a C-style library
-    of functions for direct manipulation (for those of you who prefer K&R to Bjarne). 
-
-    Here's a diagram of the class hierarchy: 
-
-      nsStr
-        |___nsString
-        |      |
-        |      ------nsAutoString
-        |
-        |___nsCString
-               |
-               ------nsCAutoString
-
-    Why so many string classes? The 4 variants give you the control you need to 
-    determine the best class for your purpose. There are 2 dimensions to this 
-    flexibility: 1) stack vs. heap; and 2) 1-byte chars vs. 2-byte chars.
-
-    Note: While nsAutoString and nsCAutoString begin life using stack-based storage,
-          they may not stay that way. Like all nsString classes, autostrings will
-          automatically grow to contain the data you provide. When autostrings
-          grow beyond their intrinsic buffer, they switch to heap based allocations.
-          (We avoid alloca to avoid considerable platform difficulties; see the 
-           GNU documentation for more details).
-
-    I should also briefly mention that all the string classes use a "memory agent" 
-    object to perform memory operations. This class proxies the standard nsMemory
-    for actual memory calls, but knows the structure of nsStr making heap operations
-    more localized.
-    
-
-  CHOOSING A STRING CLASS:
-
-    In order to choose a string class for you purpose, use this handy table:
-
-                        heap-based    stack-based
-                    -----------------------------------
-        ascii data  |   nsCString     nsCAutoString   |
-                    |----------------------------------
-      unicode data  |    nsString      nsAutoString   |
-                    ----------------------------------- 
-    
-  
-    Note: The i18n folks will stenuously object if we get too carried away with the
-          use of nsCString's that pass interface boundaries. Try to limit your
-          use of these to external interfaces that demand them, or for your own
-          private purposes in cases where they'll never be seen by humans. 
-
-    
-  --- FAQ ---
-
-    Q. When should I use nsCString instead of nsString?
-
-    A. You should really try to stick with nsString, so that we stay as unicode
-       compliant as possible. But there are cases where an interface you use requires
-       a char*. In such cases, it's fair to use nsCString. 
-
-    Q. I know that my string is going to be a certain size. Can I pre-size my nsString?
-
-    A. Yup, here's how:
-
-         {
-           nsString mBuffer;
-           mBuffer.SetCapacity(aReasonableSize);
-         }
-
-    Q. Should nsAutoString or nsCAutoString ever live on the heap?  
-
-    A. That would be counterproductive. The point of nsAutoStrings is to preallocate your
-       buffers, and to auto-destroy the string when it goes out of scope. 
-
-    Q. I already have a char*. Can I use the nsString functionality on that buffer?
-
-    A. Yes you can -- by using an intermediate class called CBufDescriptor.
-       The CBufDescriptor class is used to tell nsString about an external buffer (heap or stack) to use
-       instead of it's own internal buffers. Here's an example:
-         
-         {
-           char theBuffer[256];
-           CBufDescritor theBufDecriptor( theBuffer, PR_TRUE, sizeof(theBuffer), 0);
-           nsCAutoString s3( theBufDescriptor );
-           s3="HELLO, my name is inigo montoya, you killed my father, prepare to die!.";
-         }
-
-         The assignment statment to s3 will cause the given string to be written to your
-         stack-based buffer via the normal nsString/nsCString interfaces. Cool, huh?  
-         Note however that just like any other nsStringXXX use, if you write more data 
-         than will fit in the buffer, a visit to the heap manager will be in order. 
-     
-
-    Q. What is the simplest way to get from a char* to PRUnichar*?
-    
-    A. The simplest way is by construction (or assignment): 
-
-        {
-          char* theBuf = "hello there";
-          nsAutoString foo(theBuf);
-        }
-
-       If you don't want the char* to be copied into the nsAutoString, the use a 
-       CBufDescriptor instead.

-  MODULE NOTES:
-
-  See nsStr.h for a more general description of string classes.
-
-  This version of the nsString class offers many improvements over the
-  original version:
-    1. Wide and narrow chars
-    2. Allocators
-    3. Much smarter autostrings
-    4. Subsumable strings

-  MODULE NOTES:
-
-  See nsStr.h for a more general description of string classes.
-
-  This version of the nsString class offers many improvements over the
-  original version:
-    1. Wide and narrow chars
-    2. Allocators
-    3. Much smarter autostrings
-    4. Subsumable strings

-/*
-
-  A set of string wrapper classes that ease transition to use of XPIDL
-  interfaces. nsXPIDLString and nsXPIDLCString are to XPIDL `wstring'
-  and `string' out params as nsCOMPtr is to generic XPCOM interface
-  pointers. They help you deal with object ownership.
-
-  Consider the following interface:
-
-    interface nsIFoo {
-      attribute string Bar;
-    };
-
-  This will generate the following C++ header file:
-
-    class nsIFoo {
-      NS_IMETHOD SetBar(const PRUnichar* aValue);
-      NS_IMETHOD GetBar(PRUnichar* *aValue);
-    };
-
-  The GetBar() method will allocate a copy of the nsIFoo object's
-  "bar" attribute, and leave you to deal with freeing it:
-
-    nsIFoo* aFoo; // assume we get this somehow
-    PRUnichar* bar;
-    aFoo->GetFoo(&bar);
-    // Use bar here...
-    printf("bar is %s!\n", bar);
-    nsMemory::Free(bar);
-
-  This makes your life harder, because you need to convolute your code
-  to ensure that you don't leak `bar'.
-
-  Enter nsXPIDLString, which manages the ownership of the allocated
-  string, and automatically destroys it when the nsXPIDLString goes
-  out of scope:
-
-    nsIFoo* aFoo;
-    nsXPIDLString bar;
-    aFoo->GetFoo( getter_Copies(bar) );
-    // Use bar here...
-    printf("bar is %s!\n", (const char*) bar);
-    // no need to remember to nsMemory::Free().
-
-  Like nsCOMPtr, nsXPIDLString uses some syntactic sugar to make it
-  painfully clear exactly what the code expects. You need to wrap an
-  nsXPIDLString object with either `getter_Copies()' or
-  `getter_Shares()' before passing it to a getter: these tell the
-  nsXPIDLString how ownership is being handled.
-
-  In the case of `getter_Copies()', the callee is allocating a copy
-  (which is usually the case). In the case of `getter_Shares()', the
-  callee is returning a const reference to `the real deal' (this can
-  be done using the [shared] attribute in XPIDL).
