-//@{
+/*
+  This header defines the dynamic arrays and object arrays (i.e. arrays which
+  own their elements). Dynamic means that the arrays grow automatically as
+  needed.
+
+  These macros are ugly (especially if you look in the sources ;-), but they
+  allow us to define "template" classes without actually using templates and so
+  this works with all compilers (and may be also much faster to compile even
+  with a compiler which does support templates). The arrays defined with these
+  macros are type-safe.
+
+  Range checking is performed in debug build for both arrays and objarrays but
+  not in release build - so using an invalid index will just lead to a crash
+  then.
+
+  Note about memory usage: arrays never shrink automatically (although you may
+  use Shrink() function explicitly), they only grow, so loading 10 millions in
+  an array only to delete them 2 lines below might be a bad idea if the array
+  object is not going to be destroyed soon. However, as it does free memory
+  when destroyed, it is ok if the array is a local variable.

-// This is the same as the previous macro, but it defines a sorted array.

-//     than/equal to the second one.
-//  2) the Add() method inserts the item in such was that the array is always
-//     sorted (it uses the COMPARE function)
-//  3) it has no Sort() method because it's always sorted
-//  4) Index() method is much faster (the sorted arrays use binary search

-/** @name Macros for definition of dynamic arrays and lists

 
 

-  These macros are ugly (especially if you look in the sources ;-), but they
-  allow us to define 'template' classes without actually using templates.
-  <BR>
-  <BR>
-  Range checking is performed in debug build for both arrays and lists. Type
-  checking is done at compile-time. Warning: arrays <I>never</I> shrink, they
-  only grow, so loading 10 millions in an array only to delete them 2 lines
-  below is <I>not</I> recommended. However, it does free memory when it's
-  destroyed, so if you destroy array also, it's ok.

+// WX_DEFINE_SORTED_ARRAY: this is the same as the previous macro, but it
+// defines a sorted array.
+//
+// Differences:
+//  1) it must be given a COMPARE function in ctor which takes 2 items of type
+//     T* and should return -1, 0 or +1 if the first one is less/greater
+//     than/equal to the second one.
+//  2) the Add() method inserts the item in such was that the array is always
+//     sorted (it uses the COMPARE function)
+//  3) it has no Sort() method because it's always sorted
+//  4) Index() method is much faster (the sorted arrays use binary search
+//     instead of linear one), but Add() is slower.
+//  5) there is no Insert() method because you can't insert an item into the
+//     given position in a sorted array but there is IndexForInsert()/AddAt()
+//     pair which may be used to optimize a common operation of "insert only if
+//     not found"
+//
+// Note that you have to specify the comparison function when creating the
+// objects of this array type. If, as in 99% of cases, the comparison function
+// is the same for all objects of a class, WX_DEFINE_SORTED_ARRAY_CMP below is
+// more convenient.
+//
+// Summary: use this class when the speed of Index() function is important, use
+// the normal arrays otherwise.
