<p>
The configuration files system has two features which make
it possible to build standalone packages containing the
entire GNUstep system in a form which can be moved anywhere
and just run.
</p>
<p>
Firstly, wariables in the configuration file which define
paths, are expected to by full path specifications, except
for the special case in which they begin with dot-slash (./).
In this case the dot-slash is replaced by the path to the
directory containing the configuration file (or specified to
contain the configuration file if no configuration file exists).
</p>
<p>
Secondly, If the value specified by GNUSTEP_CONFIG_FILE (or
built into the base library) itself begins with a dot and
slash (./) then the base directory used for relative paths
is the directory containing the gnustep-base library.
</p>
<p>
So you can bundle the whole lot together in one directory,
and configure various relative paths in that directory, then
move the directory around wherever you like.
