dynamic array of strings

[Michael P.]

import std.stdio;
import std.cstream;
void main()
{
  char[][] names;
  char[] currentName;
  while( true )
  {
    din.readf( "%s", &currentName );
    if( currentName == "stop" )
    {
      break;
    }
    else
    {
      //what goes here to dynamically allocate memory for the 
     //names array? new statement? .length?
    }
  }
  foreach( name; names )
  {
    writefln( name );
  }
}
How would I go about dynamically allocating memory for the names array in the part that I commented? 
I'm not really sure about the dynamic array details in D, this is just an example to help.
