> BUILDING.txt, section 3.2 states:
> ------------------------------------------------------------------------------------
> 3.2   Create property file
> You will need to create a property file to specify
> your environment and some of your options. Do the following
> to specify your environment and options:
> (1) Find out user home directory on your system. You can find  
>     user home directory by doing echo on variable %HOME% 
>     on windows and $home or $HOME on unix.
> ------------------------------------------------------------------------------------
> In some cases, %HOME% (on WIndows) or $HOME  ($home) (on Unix) does not correspond to
the directory where ant looks for "ant.properties". 
> I recently tried to build Derby on Windows XP, and accidentally put ant.properties in
the wrong directory, causing ant to say that java.lang could not be found. On Windows XP and
2000 (and most likely all older Windows platforms as well) "out-of-the-box", there is no environment
variable called %HOME%. Creating this environment variable manually does not make any difference.
> On Unix systems, the $HOME environment variable does not necessarily always correspond
to ant's (i.e. Java's) interpretation of  "user.home". For example, if a user changes this
variable manually from "/home/username" to "/home/username/myHome", $HOME refers to the latter,
but ant will continue to look for ant.properties in the "/home/username" directory.
