-/** @name Dynamic arrays and object arrays (array which own their elements)
-    @memo Arrays which grow on demand and do range checking (only in debug)
-  */
-//@{
+/*
+  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.
